Does LibreOffice use my documents to train AI

I use LibreOffice for composing and editing the novels I write. I have believed that what I write on my computer stays on my computer unless I am publishing a comment on FB or Substack. When the novel is finished I send it to Kindle Direct. I’m trying to figure how much exposure to AI I have. I work on a MacBook Pro running MacOS Monterey v.12.7.6

No, but macOS might. Some auxiliary tools, e.g. Language Checker, Deepl, etc, might as well.

If you store your work in clouds, you never know.

Thank you for your helpful response.

Don’t store in Cloud. Thanks for your response

no.

however some extensions related to AI, if you explicitely installed them, might definitely send your content into the outer space.
