I find LLM copywriting revolting, especially Claude's and it is pretty obvious that it is Claude, and even though I might find the software interesting since I own a Clara 2E, it puts such a sour taste in my mouth that I don't want to touch this thing with a 10 foot pole.

If your software is mostly written by the slop machine, fine. I don't have to be upset about it unless I think about contributing and then notice the uncanny nature of the source code. But a website and a README is directly user facing and it is a major disservice, and in my opinion, lack of respect, to generate your website copy with an LLM.
