Not a case of unsophisticated language here -- rather, it's a case of an awkward and non-standard sentence construction, which, to be honest, I just parse as someone who doesn't speak English as their first language; ChatGPT wouldn't make this mistake.
I think the assumption that all bad grammar is the result of speaking a non-native speaker is a bad one. I work with a lot of native English speakers and they get all kinds of grammar school grammar wrong.
