This ultimately depends on how Microsoft implements the AI -- if they use well-understood techniques such as federated learning[0] and differential privacy[1], there's a strong chance for Microsoft to offer useful features without the user sacrificing privacy.
Of course, the elephant in the room is that, since 10, privacy on Windows has taken a nosedive. I'm really not sure if they'd even want to spend the R&D work on doing things The Right Way.

There are good techniques for ensuring local AI (or "on-device AI"?) is private as of now, so I'm not sure.
EDIT: (Rising to yours, too!)
> Let's say you found a local MS AI product in front of you. Do you have confidence it would not be a meaningful part of collecting user data?
With the history of privacy on Windows, I would be very hesitant that it would preserve privacy without doing some serious in-depth analysis on it, to be honest.
