What IP addresses i need to block in my firewall to block TFT from my system/router/network

I want to block Teamfight Tactics acces in both LeagueofLegends.exe and Lolclient.exe. I like to know what IP address ranges i had to put in the routers firewall settings. I tryed - didnt worked. i tryed - that shutting down the complete profile/lobby client. **I only want to block Teamfight Tactics Lobby and Ingame Client**, not normal ranked. So if anyone in my house try to play Teamfight tactics they should not find a game. or should not be abble to connect in loading screen! (Reason for that is that people in my location getting super depressed and unhealthy from TFT, so i want to block it totally from anyone using our network)
