Minecraft wiki entry for Combat, associated text: Llamas will attack the player if provoked by spitting at them for half a heart of damage one time, after which they become neutral again. They can have between 15 and 30 health points. Their extremely low damage and lack of pack mentality basically nullifies them as a threat to any player with weapons or armor of any level. However, if the player happens to find themselves completely unarmed and unprotected against a llama with half a heart of health left, its spit can be dodged by sprinting sideways to the llama.
