I'm working on the UX and UI of a new AI product, but the structure, implementation, and how the system will function feel blurry. How should I approach this?

I would use @Dan Winer's See/Do approach: https://www.linkedin.com/posts/danwiner_ux-uxdesign-productdesign-activity-7095009958122987520-8vpj?utm_source=share&utm_medium=member_desktop Use this approach OR user flow approach to map the whole system and go from there. You'll need to do some sort of audit of the UX then the UI. That way you can gain an holistic view of the product.
