Precise answer: we don't know if any Mesozoic dinosaurs could do this.
Realistic inference answer: almost certainly not!!! There is no evidence of
tool use in Mesozoic dinos. In fact, there is only
limited tool use in most groups of modern birds. And corvids are among the
smartest living birds with very sophisticated behaviors.
So extrapolating that _Velociraptor_ or _Coelophysis_ or _Plateosaurus_ could
have used tools, and learned from their relatives,
would be like using the known presence of learned tool use in modern catarrhine
primates (Old World monkeys and hominoids) and
extrapolating that Paleocene primatomorphs or _Eohippus_ or _Morganucodon_
