I'd argue that when the code is part of a press release or corporate blog post (is there even a difference?) by the company that the LLM in question comes from, e.g. Claude's C compiler, then one cannot reasonably assert they were "not using the tools correctly": even if there's some better way to use them, if even the LLM's own team don't know how to do that, the assumption should be that it is unreasonable to expect anyone else to how to do that either.

I find it interesting and useful to know that the boundary of the possible is a ~100kloc project, and that even then this scale of output comes with plenty of flaws.

Know what the AI can't do, rather than what it can. Even beyond LLMs, people don't generally (there's exceptions) get paid for manually performing tasks that have already been fully automated, people get paid for what automation can't do.

Moving target, of course. This time last year, my attempt to get an AI to write a compiler for a joke language didn't even result in the source code for the compiler itself compiling; now it not only compiles, it runs. But my new language is a joke language, no sane person would ever use it for a serious project.
