It's likely that but for LLMs, the article would not have been written. I'm glad it was written. It's also true that it's unpleasant to read LLM-written prose for those of us who have to read it all day for work.
I don't think it's shallow because writing quality isn't important, I think it's a shallow dismissal of the writing quality because it doesn't discuss anything interesting or substantive about the writing quality.
Also, what about the other guidelines? Comments should meet all of the guidelines, not just some of them. (I do get that some of these are borderline.)
If you feel a given comment is not within community guidelines you are free to flag it. I do not believe that we agree about the substantive value of noting an article was written with the heavy assistance of an LLM. I usually look at comments prior to reading an article; it's an effective time-saving measure.
I do not accept your attempt to make a blanket ban on noting an article was LLM-written.
