You should have responded something like "its fine on my end, you are not following the documentation i've written please take any complaints up with [Manager]" and then left your manager to deal with the problem they caused. Or lodge a complaint to the person above them. If they think its ok to run docs through an AI and hand it out uncritically they should be fired on the spot.
