The only always online games I’m aware of are by Blizzard. Nearly every Nintendo game, playable offline. Elden Ring, Armored Core 6, Monster Hunter World/Rise, God of War etc are all playable offline. Then there are games like Dragon’s Dogma where you are in your own world and you never have to interact with another player outside of using their pawns which are AI controlled.
In D4, you are shoved into an open world and players are around you whether you want them there or not and you have no option to disable that. This alone should be the red flag for every solo only player.
