Leela: Are you blackmailing me?

Professor Farnsworth: Hey, unless this is a nude love-in, get off my property.
Hippie Protester: You can't own property, man.

Answer: Yes Leela knew from early on that Fry had feelings for her. They were pretending to be a couple in 'A Flight to Remember' from season 1 and Fry tried to get on dates with Leela ever since. She just didn't show signs of the feelings maybe being mutual before some of the later episodes.
