I do not use the Imperium as a setting, and never have.
From world generation since the early days, The Tech level of the world has been modified by the presence of a Starport, but it often turns out that if you use the rules straight, even since the early days, worlds that are Earthlike are relatively lower tech in general, while worlds that are worlds that are very earthlike, with a moderqte popuation (read Colony) are not going to have the tech levels that an Asteroid Belt, or somall world with little to no Atmosphere to speak of, or something corrosive or insidious, with the exception of huge populations, which seems to be driven by the idea that you cannot have Pop C without higher tech, or you will get overpopulation and dieback (which isn't in the rules)
I would not say they are not related, they are linked withing the rules from the chart for Ports and Tech.
That being said, they do not "Have" to be related.
You could have by fiat an A port on a world that is low tech jungle, with only plant life going for it, if the story the referee wants to tell is going that way.
Otherwise it's a justification, that I come up with when I am not choosing by referee mandate what the world is. sometimes I get better ideas by coming to grips with the Why is this true for this world?
The different justifications will range across the board, based on the referee's perception of what the campaign is about. Even perceptions of what the Imperium is, or should be can vary wildly, from campaign to campaign, even playing it rules as written.

"Imperial starports (A/B at a minimum) should, I think, be a minimum of TL-13, as that is the Imperial standard, and starports being official Imperial facilities they should conform to the standard tech level."
If you go by the charts, A is minimum TL 6, B is minimum TL 4. The other factors that can drive it up are Desert or Water World, Asteroid or Moonlet, so to speak "hard to breathe atmospheres", Huge population, or Balkanized. Combined, all of these can infer or cause a TL that exceeds 6, with no starport.
Populations max out at 10, unless you use the Space Opera / Hard Science Rules, which can give you Pop 11 (B) with a nice clean atmosphere..
So you could have an Asteroid Belt, Pop A, Balkanized D port, TL 8. How does that work?
The locals have to literally ship everything in in massive waves of ships, that do not have enough Berths. Local guys can get work by running impromptu cargo shuttles that drop off ores, and pick up food and water and luxuries shipped in, and distribute it to little enclaves all over the belt.
I agree that Imperial standard TL is 13. To me if every world with a big port is TL 13+, it becomes a sort of vanilla setting. I can go to the USA and eat at McDonald's. I can go to Thailand and eat at McDonald's. If your perception of the Universe you want to run is such that the Imperium decides We are here, were are what passes for imperial culture, then it is going to come out like that. This is the standard, and we shall uphold it.
But the contrasts and flavors come from the setting that is at variance. It is a mystery to be solved. A situation that we do not initially understand, but might be compelled to discover. If we arrive at a moderate pop ocean world, but the port is B, tech is lacking as players inside that setting do we say, oh well, referee rolled a "1" on the TL die roll?
We find out what creative story the referee is telling us... it's a small research station, the Port is B because they ship agro products like what passes for whale meat off world, and import speed boats or submarines, or hydropower modules or wind vanes or.. whatever.
I like and prefer that the tech does not match. That means that I am encountering the unexpected, which means a mystery to be solved. if we know the outcome, or we expect something, and get that something that we expected, there's no dramatic tension.
