Llamas are bugged you can tame them but you can not put a saddle on them.

Please do not mark unreleased versions as affected.
You don't have access to them yet.

Saddles cannot be placed on llamas. You can only use chests and carpets. They can't be controlled while riding. More information: http://minecraft.gamepedia.com/Llama
