Technically yes, but in practice no. You would need an AI package for a whole player squad, and it cannot be added later, so you would need a start where it is already included. And before you jump to 'that's easy'. remember AI packs are meant for NPCs, that entire squad would then have automation all day, running randomly to loot people where-ever you are. They would also refuse to do work in the base, cause the AI pack conflicts with player orders.

Meaning you would have to start a new game with x looters (how many you want) and one leader character, park your looters somewhere safe and hope they won't run into enemies why you try to begin your game with the one leader. (you can move people to a second squad to get rid of the AI but the moment you remove all characters from the original squad you no longer have access to the AI)

You would still have to feed them all, unless they are skeletons of course.
