It's pretty clear immersion is the best path.

Using AIs conversational skills seems like the best way to employ AI in language learning.

Immersion will absolutely get you speaking and listening fluency (with enough time). Reading and writing? That's another matter. If you're coming from a Latin alphabet language and trying to learn to read and write Chinese or Japanese then you've got a lot of study and practice ahead of you. Acquiring the knowledge of several thousand Chinese characters (needed for both languages) can only be done through deliberate study.
