"Regrading might not be a bad thing, if a professional suggested it. It

certainly wouldn't hurt, as long as it didn't mean removing/replacing
a lot of landscaping."

Not only is it not a bad thing, it's very likely a necessary one,
regardless of landscaping, especially if a home inspector identified it
as a problem. If the grade is in the wrong direction, water is being
directed toward the house instead of away from it. While the effects
may not be immediate, or even obvious, this can lead to a whole host of
problems, some of which are not even obvious.
