Pirate it

>I know some might wonder about third party clients or as some called them it seems ,hacked clients , but those don't support LAN/multiplayer it appears.

They do of course if the server is also cracked. Host on your own, which I assume you already do.

Offline mode only means you can't auth with mojang servers, there are many minecraft servers that use their own authentication via server plugin instead of mojang account.

Btw are there any opensource clients that support offline mode?

MultiMC.

The game is easier to run on Linux if you pirate it anyway thanks to the awful new launcher they made.
