No idea how we will achieve this but it's a request nonetheless

Would need a custom drop setting such as:

enable-looting: true

Then would need to get the attacker and check the equipped item. If it's enchanted with the looting enchantment, get the level then depending on the level, increase the drop chance based on the logic here: https://minecraft.fandom.com/wiki/Looting

Oops, it affects item amount, not drop chance
