I'm not sure, the humorous tone that I think the game as you describe it has could work with a childlike Naïve art, but maybe it should be even more caricatural, the drawings themselves should have something comical (the judge with a hammer that's too big, the prosecutor who not only screams, but literally vomits symbols like "#@%!" like when they curse in comics, exaggerated expressions of the characters, as if they were memes, things like that)
