This is exactly my problem with LLM C code, lack of confidence. On the other hand, when my projects get big enough to the point where I cannot keep the code base generally loaded into my brains cache they eventually get to the point where my confidence comes from extensive testing regardless. So maybe it's not such a bad approach.
I do think that LLM C code if made with great testing tooling in concert has great promise.
