Considering these villagers can own pet dinos that spawn with them, dinos do spawn in game; but unlike regular animals and mobs, they are one-time spawns that generate with the world, just like Villagers, world-generated Iron Golems, Guardians and Shulkers. There would be a limited number of these dinosaurs per world, and after it is fully generated no more will spawn; therefore, you would have to create them in order to get more.
