Also take into account that aside from handlers and vets its really not essential to other park staff to know what gender an animal in the park is. Look at Nedry in the first film, saying to the Dilophosaur "Nice boy... nice boy. Nice Dinosaur..." and "I thought you were one of your big brothers..."

Not only that but on multiple occasions in the first novel the two Tyrannosaurs are referred to as "He" by multiple characters who do know better - for example Arnold says in reference to monitoring the juvenile Tyrannosaur "You get a sense of his home range over time - He's young, so he says close to the water. And he stays away from the big adult Rex."

Think of it as being like how some people refer to their car or a boat as a "she" - neither vehicle has a gender but people still refer to them that way.
