I don't think there really is any clear cut way to dealing with the bots, maybe what the GM can do is mark the bots for us if they see them (since their hands are tied in other ways), and we can just PVP/tele death them to some hellscape prison whether they are found out in the field or in a town (imagine casting HOLY in one of the towns, that would be a spectacle lol). Treat them like actual monsters we can just defeat.

I know my suggestion is silly and not a permanent solution, but it would be a rather fun way to getting rid of bots in a comical way.
