Even if you tell the LLM not to use LLM pros they (still) do it. If you feed the Wikipedia article on signs of AI writing and tell them to use none of those signs they will also (still) do it. I have tried (many times) to get an LLM to explain a concept to me, or a process, or an algorithm or what have you, and every time they cannot help themselves. Either they use LLM pros, or they get so verbose that it all just becomes noise and I spend more time filtering out unnecessary jargon than I do reading let alone learning anything.
