So, the block has a "textureAll" which should texture all faces, but the "main" one is missing?
event.create('food_off', 'cardinal').textureAll("kubejs:block/food_off")
.soundType("metal")
.displayName("F.O.O.D")
// .textureSide("north", "kubejs:block/food_off")
// .textureSide("down", "kubejs:block/food_off")
