I think soon. Because when you think about it.
• The therizinosaurus is one of the most requested dinosaurs in game,.
• It has some notable lore in the Jurassic world movies (the claws of the indominous rex was from the therizinosaurus)
• There is a
hybrid that is shown as an easter egg in the movie that is notably therizinosaurus. So if future hybrids are planned, a therizinosaurus hybrid may happen.
As of now, only the devs know. Plus there is a super secret dinosaur leaked accidentally last week (They should be more careful, honestly). So we could wait and see what we have in store
