People heavily overestimate how difficult these are to tame. Just use 4 metal billboards and a large bear trap. This will only cost you 146 metal ingots, 40 cementing paste, 10 hide and 15 fiber. If you demolish it afterwards it will cost half that number. The taming effectiveness barely goes down when you use mejoberries, so use those. Do not feed it narcotics, feed it mejoberries instead. The reason for this is; the torpidity on narcoberries goes up slower than narcotics, this means they will keep the therizino asleep for a longer time period. The saddle for it is unlocked at level 69 (nice), and that's all you need to know.
