AI personalities is for dialog in SP when you don't want to talk to yourself all the time, I don't think D:OS ever will support behavior scripts that are complex enough to do what you want Ellary
After all, you control the characters even with personalities ON at all times 100%. It's not like in BG2 where you could check "Companion AI" and they will actually do stuff (mostly) without your input.
AI Personalities (as they are now) are basically just "How is this character going to respond to situations in dialog"
Either way, I hope it's not gonna be only "RANDOM" on release. ^^
