> A key part of reviewing a paper is reading it without preconceptions
I get where you are coming from here, but, in my opinion, no, this is not part of peer review (where expertise implies preconceptions), nor for really anything humans do. If you ignore your pre-conceptions and/or priors (which are formed from your accumulated knowledge and experience), you aren't thinking.
A good example in peer review (which I have done) would be: I see a paper where I have some expertise of the technical / statistical methods used in a paper, but not of the very particular subject domain. I can use AI search to help me find papers in the subject domain faster than I can on my own, and then I can more quickly see if my usual preconceptions about the statistical methods are relevant on this paper I have to review. I still have to check things, but, previously, this took a lot more time and clever crafting of search queries.
Failing to use AI for search in this way harms peer review, because, in practice, you do less searching and checking than AI does (since you simply don't have the time, peer review being essentially free slave labor).
By "without preconceptions", I mean that your initial review should not be influenced by anyone else's opinions. In CS, conference management software often makes this explicit by requiring you to upload your review before you can see other reviews. (You can of course revise your review afterwards.)
You are also supposed to review the paper and not just check it for correctness. If the presentation is unclear, or if earlier sections mislead the reader before later sections clarify the situation, you are supposed to point that out. But if you have seen an AI summary of the paper before reading it, you can no longer do that part. (And if a summary helps to interpret the paper correctly, that summary should be a part of the paper.)
If you don't have sufficient expertise to review every aspect of the paper, you can always point that out in the review. Reading papers in unfamiliar fields is risky, because it's easy to misinterpret them. Each field has its own way of thinking that can only be learned by exposure. If you are not familiar with the way of thinking, you can read the words but fail to understand the message. If you work in a multidisciplinary field (such as bioinformatics), you often get daily reminders of that.
