Currently with type_hints enabled, we do not explicitly declare the type of generated all_structs. It's meant to be a list of different types, but that will cause problems, as the generated code is usually like this:
The first append infers the type of all_struct to be list[Type1], so mypy would start complaining from the 2nd append as the type is unexpected.
Explicitly declare all_struct to be list[typing.Any] instead, which fixes the issue.
