Yes, oui, yes, absolutely.
No compromises on format . Generated content must be in ODF format, just like any other content, and must retain its structure, styles and semantics. An assistant that generates documents in a proprietary format perpetuates content lock-in.
So they won’t be dumping ODF for Markdown just to make the whole suite LLM-friendly?
Say it ain’t so! 
From the linked page:
In the meantime, users who wish to use AI features can install one of the available extensions, which can be found either on the LibreOffice extensions website or distributed independently. Most connect to a locally running model via Ollama, LM Studio or another OpenAI-compatible endpoint, which means the document never leaves the computer.
I don’t think its actually “no AI.” It’s “use a local AI” or maybe “use a local AI and maybe a cloud AI.” I like that it’s not forcing anybody to use AI when writing.
