My wife translated some text she had written in her own language to my native language, as she didn't feel she could do it. I found grammar errors, surprising ones. I found places where pronouns were used so far into the sentence that a reader would be lost finding what that pronoun actually referred to. And more. In the end I rewrote the LLM-generated text myself, many pages of it.
