Gen4 no power- how can you put in neutral?

How long was the tow?

Did you ask the shop for anything more specific about what was damaged? A stator, being stationary, doesn't usually have a bearing.

Rather than generalizing about any "eCVT transaxle-based car", it's better to be very specific, because there have been significant changes between generations in just how the oil gets circulated. There is a summary of those differences here in this thread, up at ➡post #27⬅ (which in turn links to a more detailed post kindly made by KMO).

The earliest generations had an oil pump driven only when the engine runs, which would be a definite concern for long tows. The generations that introduced longer EV-only range naturally had to make changes there.
