Most non-playable factions don't expand. The main exception in TR is the Yevethans who become hostile during the Black Fleet Crisis, which I believe is Era 5-ish on the progressive maps. If you also play Fall of the Republic, the other EAWX mod, the non-playable CIS companies expand but generally don't attack each other or the playable Confederacy faction.

What's strange to me is even though there are examples of aggressive non-playable factions, not a single playable faction defaults to passive when not controlled by the player. Given how lore-accurate the rest of the mod tries to be, I would appreciate a neutral Hutts / Hapans / CSA when not playing as them myself.

It's a game first. Those factions have a more defensively-oriented AI but if they just flat out didn't attack then they're just territory which would be ignored most of the time, and that's a huge chunk of the territory (which is determined in each map by trying to make as many viable factions as possible)

My personal experiance with the yevethans has been that they are only aggressive against the player. Though I can not say if that is because the AI bordering them actually has a permanent fleet presence the yevethan AI is not confident in beating or if it is coded to only attack the player.
