As suggested by kezabelle, I have made the changes to the code and used the type match Dict[Type[Model], Set[Model] | List[Model]] instead of typing the values as Any in the dictionary. Would appreciate it if you could review the changes and let me know if there is anything else that needs to be done.

Thanks.

FWIW the downside of using Model instead of Any is that when you want to access the fields and methods of a particular model subclass (e.g. auth.models.User), mypy won't let you do that without an explicit cast() or isinstance() check. But either is fine by me.
