How much is post processing AI?

I am the consumer and booked a photographer for a family shoot. She was vetted on a FB group and is also the official photographer for a high end hotel in the area.

She generally did a great job but several of the returned photos look quite AI generated. I don't really like them.

So the question is am I right to feel this way? or is AI so prevalent in post processing that is just what happens? I really don't know if I should tell her or just leave it.
