You need to read the older Traveller K'kree sourcebook. They HATE carnivores only tolerating human contact because they have no means as of yet to get them. Their whole science is towards eradication. Jump was created to find and kill more carnivores. They are instinctually compelled.
I have the 1984 Alien Module from GDW (Written by Andrew Keith and Loren K Wiseman). I went through a scanned copy of the module looking for references to carnivore and G'naak when writing my post.
On page 3, their basis for an army (and military in general) was based on the concept of hunting for vermin (carnivores that can threaten the herd). There is a cultural preocupation with tracking down potential dangers to the herd which drove all of their technological development. This isn't just military development. It is not described as a purely military based activity. Agriculture, for example, was invented to provide a more stable food source (protect the herd from hunger/starvation).
The focus here cannot be stressed enough - the protection of the herd. Not every carnivore in the galaxy is a threat to the herd. A carnivore in the vicinity of the herd may pose a threat that would need to be dealt with. They wouldn't cross half the galaxy to see if there is a carnivore there - they will patrol their borders and watch for any potentially threatening creature approaching their space and weigh the threat. A fleet of Vargr corsairs would get in a fight right away. Maybe any Varger might. But a barely armed tramp freighter with a handful of humans on it may get through with friendly words and intentions.
A case in point. On page 10 of the Alien Module it describes the treatment of humans in the Two Thousand Worlds. There are a couple of paragraphs about the need to adopt a vegetarian diet. The K'Kree "distrust all strangers and dtest those who eat meat. Humans voyaging in K'Kree space will have little if any chance to deal with the Centaurs unless they adopt the right attitudes or customs. First and foremost, a change in diet is required."
Okay, so far that isn't inconsistent with what you said, but it goes on to say that it takes three days to eliminate the odors associated with the consumption of meat and says "Until these odors are completely gone, K'kree reactions will be very negative and the human will find a poor reception up to that time". Note that this is a golden opportunity to say something like "will drive K'Kree into a homicidal frenzy", but it doesn't. It just says a poor reaction. Says nothing about any violence. Seems more like "I don't like how you smell. Get out of my office!"
Of course if you start a fight with a K'Kree while smelling of meat - the smell may compound things into a view that you are just like the G'naak. I found nothing in the Alien Module that says they are driven to kill all carnivores - just that they are driven to protect the herd. So until you represent a clear danger to the herd you may be able to get by.
The K'kee are dangerous not because they have an irrational hatred of us. They are dangerous because they have a cold rational approach to eliminating threats to their herds.
Violence for humans can be an outlet to release tensions. Two men might be driven into conflict which they seek to settle with their fists, a dominance struggle that has played out many times for thousands of years. There are rules. Hitting from behind appears weak, and the purpose is to show strength and superiority. When one backs down the other will generally stop hititng him (maybe a punch or two extra to make the point first) but we are psychologically conditioned to accept surrender.
The K'kree have no such boundaries and rules once you cross a line where violence is needed. Walking around smelling of meat is offensive. An insult. You will hear "get out of my office. Get out of my shop. Leave my neighborhood. Go back to your ship." Maybe physical threats will be involved if you hang around much longer, maybe not. But if you are alone (another taboo - loners are insane) and you pick a fight with a K'Kree who threatens you, this may be enough to push the K'Kree to violent action. You are now an insane loner G'naak who is attacking a member of the herd.. And now you are up against a group of them because they will reach this decision together or follow those who lead. They don't act alone. And they don't stop. They don't understand submission rituals that end fights without bloodshed or death. Once you are G'naak you can't surrender and live. Maybe you can run and escape. If you run far enough they may give up pursuit. But if you stand and fight and kill members of the herd you will find yourself up against more and more and more of them.
I think the nearest analogy for a meat eating human in K'Kree space would be a black man in 1960's Mississippi in a white neighborhood during a Klan rally. Not guaranteed he will be lynched but he knows he needs to really watch his behavior and not make waves if he's going to survive this.
Actually, a pretty good analogy I think. The K'kree are the ultimate racists.
