Minecraft wiki entry for Gathering_resources_on_peaceful_difficulty, associated text: Llamas are technically tamable mobs, but they are also neutral mobs, as they will spit at the player, dealing half of a heart of damage, if attacked by the player. They are the only mob in the game that will do damage to the player on Peaceful difficulty. However, this can easily be avoided, as llamas only drop leather upon death, which are also a drop from both cows and horses. Llamas can be equipped with a chest for storage, and they can be equipped with a carpet for decoration. Llamas will only spawn in savanna and mountains biomes. Trader llamas also spawn anywhere with wandering traders, even underground or in mushroom fields biomes.
