They can sponsor any Italian team, but if their license prohibits them to serve Italian users, there is no way they can bend that ToS and risk getting into legal trouble by serving Italy illegally. Sponsoring a team from a country is entirely different from allowing users from that country to play on their platform. Again, it's more of them having limits on their license rather than them not wanting to do business with you guys. Trust me, they want to serve as much countries as they can IF they can.
