But they're still acting on the company's behest. If I hire a jerk to work tech support and they insult or cause damage to my customers, I don't get to say "shrug, they don't represent my company". Of course they do. They were on my payroll. I think it'd be pretty easy to argue that the AI was performing the duties of a contractor, so the company should be responsible for its misbehavior, just as if a human contractor did it.
