No solution, unfortunately. Even if you delete the page or some of the revisions, deleted contributions are still counted. That wasn't always the case; it used to be they would be removed from the count if the revision or entire page was deleted.

Is it just the number that bothers you, or does this user do it to a degree that it floods Recent Changes with nonsense edits and disrupts regular browsing of that page? That can be explained as vandalism, but as you said, blocking is not an option here, so I won't suggest that. Have you talked to the user about your grievances? Explain it's bad etiquette. Maybe it helps, maybe it doesn't. Sadly, that's the only thing I can think of.
