Different sort of relevancy. It is relevant that generating good looking bullshit became much faster and cheaper to the overall process because it means that assessing someone's contributions is more difficult, but it is not relevant when you're giving feedback on the hypothetically critical feedback you received in the first place. All that matters there is whether it was useful or not. Someone submitting AI generated reviews becomes relevant again when deciding whether to keep a reviewer around - a pattern of useful looking but useless and time wasting 'contributions' is relevant. Basically don't over index on whether someone is using AI to be a shitter, focus on the problematic behavior.
