How do you know that bipedalism and carnivory are not just Theropod traits?

Just by observation, it can easily be noticed that bipedalism and carnivory are traits of numerous different animal groups, not to mention the fossil remains of the top of it.

Explanation:

Theropoda is a group of dinosaurs that has hollow bones and three-toed feet. They were generally dinosaurs that were bipedal, with the larger specimens have front limbs that have been significantly retracted. Most of the species were also carnivores, and some of the most famous dinosaurs fall into this category, like the T-Rex and Velociraptor.

Bipedalism and carnivory though are not traits unique to the Theropoda only. We just need to look at ourselves and we will find the first clue in us, as humans are bipedal. And it is not just humans, but we also have the kangaroos, wallabies, kangaroo rat, and many more extant and extinct species. When it comes to carnivory, again, we don't have to look far, as the two most popular pets in the world, the cats and the dogs, are carnivores. Some other examples of carnivores are the tiger, wolf, jaguar, cougar, Tasmanian devil, polar bear, leopard seal, and many more.
