I can't see any reason to prevent anyone from building an in-system robotic ship. We build them all the time here and now (Voyager, Cassini, Curiosity, Opportunity, etc).
Not to mention the regular HTV resupply missions to the ISS, all of which are unmanned and automated.

Personally I think the biggest problem with automated ships in Traveller is cultural, apparently Humaniti doesn't particularly trust robots. You'll note that although almost any crew position on a ship (including piloting & astrogation) can be automated with expert system (you'd need to install additional computers to run all this software) so the technology to do it exists. But there seems to be a real bias in the 3I against it. You see a similar bias about robots in general (though more recent publications seem to be softening that).
The core rules (Traveller Core, p146) makes it clear any crew position, from gunner to engineer to pilot can be automated. Based on that I would say it would be possible, if you installed enough computers with the right software to fully automate a ship. However, Tech restrictions will limit you to Intellect/3 and Expert/3 systems (Traveller Core pp92-93) unless you have access to TL16+ software; which is available on certain worlds (i.e. Vincennes, Deneb Sector; Deneb Sector book p34).
However, while I've allowed such highly automated ships in my TU, I've also utilized the apparent bias; having 3I citizens/authorities react with suspicion and even fear of such a ship (even if the captain were a sophont commanding the ship). Generally such ships had trouble attracting passengers (especially high passage) and even cargo (people fearing such a ship might not be reliable). Pirates sometimes thought of such a ship as an easy target (i.e. thinking computers aren't as good as sophonts, no crew / marines to defend the ship, etc.); which generally proved to be a fatal mistake (internal security tended to be lethal). I've also played it that the requirement for a human captain/pilot was a
legal requirement in the 3I, not a technological / jump drive requirement. If you have Book 9: Robots (and can get past its flaws), robots are generally a cheaper way of automating a ship, and they can have up to skill level 3 (or pick up Special Supplement 3: Vehicle Upgrade Manual and use the rules for making a vehicle into a robot to automate your starship).
