I figured out how to add/remove loo but need to add lootingEnchantBonus

CraftTweaker's entity drops API doesn't work like that, you can't pass it objects from LootTweaker's loot table API. They're completely separate systems.
Don't try to learn ZenScript by just guessing what works.
The docs for beginners are lacking, so either find me on my discord when I'm awake (8pm GMT - 9am GMT); or join the CraftTweaker Discord which is big enough to have someone who can help you awake whatever your timezone is.
