Trainers are only made if the game is popular with WeModders. The WeMod software automatically detects how many WeMod members have the game.
Saying that, this appears to be a multiplayer game that, at this moment in time, does not have any single-player offline features, according to a quick search. Trainers are only for offline single-player games, not multiplayer games.
Really hoping this one gets covered. Trying to find someone to play with is next to impossible and I’ve not been able to solo the first boss at all. Pretty much the exact case of why I use WeMod. lol
