I would not deal well with a therapist who thought they got to tell me what to do. I certainly don't view a therapist as a guide.

I would simply tell them no. But I also would not let them guide the conversation if I had something I wanted to say, or I would ask what they were doing and why.
If you don't like it, just tell the guy to stop it is what I would do. Seriously - you are hiring him and if you want it done differently -why not tell him.
