Hopefully the full implementation will turn them non-hostile, maybe with an initial dialogue (easy, persuasion or intimidation) check to convince them to not resuming fighting.
seems impossible to do when you can knock out every single npc in the game
Doesn't every NPC have a "hey, I've been stolen from!" dialogue where they come seek out the player? Then you make a check to convince them you're cool?
Just do the same. If you pass, set hostile_flag=false
