Python: Get top n key’s with Value as dictionary
Consider changing the dictionary in place if that dictionary won’t be needed anymore in memory, as dictionaries in python 3.8+ or 3.9+ (I don’t recall) have order capabilities so far as I am concerned.

First, a short style comment: In Python, range has an implicit 0 as its first argument, so range (0, n) is the same as range (n). You are doing this very manually, while it can be a bit faster when using built-in functions. I would first sort the items of the dictionary by the length of the values. (You cannot avoid going over the dictionary once.
