Is it possible to play Call of Duty WW2 online with a friend on PS4? Not 1 on 1 or something, but to play together in a team against these bots? And everyone on their own PS4 with Ps Plus membership. So best in a team against these bots, just like you would play the story, just in pairs.
Should go over the private game option
Of course you can. In the main menu of the multiplayer there are links "Custom Game" at the bottom and there you can play against bots. You have to invite your friend first before you start "Custom Game".
