I think you overestimate the extent of Author Services' involvement. It's near nil; there's no back-and-forth; you just send them your article and they send back a version with fewer grammatical/textual errors and correct formatting for the journal. It's a lot like an LLM, just slower and considerably more expensive. Also, you severely underestimate the ability of the authors to edit and verify the correctness of their own work. They wrote it in the first place, after all. They know, better than anybody else, what's important to convey. What's more, this editing step happens before peer review, so if the paper is junk or has glaring errors it'll probably be turned down by most respectable publications. Even the marginal publications won't publish stuff that's really bad.
