As the title suggest, unfortunately I couldn't find any mods that serve this simple function. There are other mods that do that, but unfortunately they tend to give AI other buffs, while without forcing AI to sally I found any campaign post-early game become literally unplayable with AI just hiding in settlements and forcing me to spend 17 turns in a siege or fight a very tedious seige battle... every time I try to take a settlement, which is simply annoying. There was one good mod on SW that did this, but unfortunately it disappeared from launcher, presuming it was pulled off Steam, and the other mod that exists needs an update.
