You need to stop saying "all archangels are angels but not all angels are archangels", because it doesn't pertain to this. Death said Levithans can kill angels. Archangels are a type of angel. Nowhere is it implied that they are an exception. Archangels are angels, which Levithan can kill. By your "logic", we can't say that an archangel can smite Ruby. Just because they have outright said it in the show doesn't make it any less true. It's the exact same thing with this.
