Bipedal, lizard-hipped, meat eating dinosaurs are all theropods. However, some theropods eventually evolved to eat plants and/or to be bird-hipped.
Those would be called theropods. Though they were never man-eating as there were no humans around at the time.
Yes There is the bird-hipped dinosaurs and the reptile or lizard-hipped dinosaurs. These were further subdivided into smaller groups.
Saurischians

Under current classifications, no. Velociraptor was a very birdlike but not really a bird. However some scientists have suggested that velociraptor and its close relatives were flightless birds.
Theropods are lizard hipped, bipedal dinosaurs with three clawed toes that touched the ground (many had a fourth toe that didn't reach the ground called a dewclaw). Most of them, with the exclusion of birds, were meat eaters.
The two major groups of dinosaurs are the Saurischia (lizard-hipped dinosaurs) and the Ornithischia (bird-hipped dinosaurs). These groups are distinguished by differences in their pelvic bone structure.
Ornithischians with a hip structure similar to that of present day birds.
Most dinosaurs were not carnivores. It's always that way with animals because there's a lot more vegetable matter in the world than there is meat, so most creatures feed on plants.To be a little more specific, there were two great branched of dinosaurdom, the lizard-hipped and the bird-hipped. ALL of the bird-hipped were plant eaters and MOST of the lizard hipped were as well.It's easier to remember the few that WERE carnivorous. One good clue is that they stood on two legs (some two-legged, or bipedal, dinosaurs, however, were plant-eaters).There were four-legged meat eaters, like Phobosuchus, but these were not dinosaurs.
Apatosaurus was a lizard hipped dinosaur. Birds evolved from lizard hipped dinosaurs, and thus they are the closest living relatives of all dinosaurs, including Apatosaurus. All birds are equally related to Apatosaurus.
