Evidence is limited but orcas might also do that to great white sharks. The orcas seem to sometimes work together to exterminate sharks from an area in a way that goes beyond just hunting them for food.

Lions and Hyanas are well known for trying to exterminate each other's cubs (they rarely eat the carcases). Adults mostly avoid fighting each other as its too risky.

I think the difference is extermination from an area versus exterminating a line. Humans and chimpanzees will exceed their territory to eradicate foes. That, per this primatologist, is a unique adaptation.

Killing off another species isn't that much like genocide, which involves killing off a rival genetic line of the same species, but orcas do that too: https://pubmed.ncbi.nlm.nih.gov/29559642/
