From your feedback, we learned that many of you are saddened by the lack of a special button for LAN game in the main menu. Individual button for LAN play is not needed, because you can create a session on the local network directly from the general lobby in the "Network"
To do this, create a "new game" secured by the password and send password only to people from your local network. After starting the session, the game will go through a local network and ping between the participants in the session will be within 10ms.
Enjoy the game.
