To add to my post earlier, I'll explain a bit more about the molar thing. I had wanted to write about this last night, but I was too tired.
Anyway, while dinosaurs don't have, far as I know, any full carnivores that have both pointed teeth and molars, it is true that in mammals, we do have those. And yes, some herbivores will have sharp teeth. But if you look carefully at the teeth as a whole, you'll have a better idea of what they ate.
Here is a skull of a wolf, a carnivore:

You'll also notice that, despite all of them having sharp teeth, they each have different diets, and you can see that reflected in the back teeth. Notice how the wolf has mostly pointed teeth and very few molars, and the molars it does have are greatly serrated. This is ideal for tearing off meat. The wolf doesn't worry about chewing its food. It bites, swallows, repeats.
The muntjac deer, on the other hand, has many molars and while they do have a pointiness to them, it's subdued compared to the teeth of the wolf, and they are flatter. This helps with crushing and munching tough plants in its jaws.
Finally, the bear. Its teeth are a mix between the two. It has sharp canines perfect for tearing into flesh, but it has more molars than the wolf, less than the deer. A couple of them are flatter for grinding plants, but a couple of them are slightly more serrated. Not to the same degree as the wolf, but enough that it could use those teeth to help rip off flesh.
Now it is true that Rinkus and Sierra could still eat plant material while having nothing but sharp teeth, since I believe that's what they believe troodon did (

Having nothing but pointed teeth is not good if you're going to be living off of nothing but plants for all your life. You need something to help pulverize the plants. Rinkus and Sierra could be omnivorous, but they probably aren't leafeaters.
I do hope that clears up any confusion regarding the teeth.
You can continue believing they are leafeaters if you want, but don't expect others to agree with you.
