RoomListUseCase Exception ResponseFailure can be improved

return res.ResponseFailure.build_system_error(

I think this could be replaced by:

return res.ResponseFailure.build_system_error(exc) as Response failure can be built from an Exception so you won't repeat the piece of code building a ResponseFailure from an exception in use_case

(i didn't check the git history, but i think this was your intent to separate the buisness logic in use case as much as possible from the «pipe logic» of building a Response from an Exception )
