I wasn’t able to find a reference to the park’s inaccurate name in either book or film, but this Reddit post explains my feelings about it:

Okay, you’ve noticed that the name given to the theme park by the arrogant old man who thinks he can harness the forces of nature for fun and profit does not accurately reflect the animals bred to live in the park. Now take that next interpretive step.

Everything that goes wrong is entirely the fault of a billionaire doing billionaire things.
