Llama is so much like a horse or a camel, all players who meet them in the world of Minecraft PE, they are trying to ride. However, without installing the mod you will not be able to do this. The situation resembles the one that occurred after the appearance of camels in MCPE, because it, too, was impossible to ride as long as the Creator of the addon has not introduced this feature.

For this, try to ride it until then, until you see an animation of flying hearts. Then, remove from your inventory on the pad and shift it to the only active slot equipment of your new pet. Carpet will be replaced by the saddle.
