Attempting to hire a hitman who turns out to be an FBI agent is still a crime, and likely not entrapment in the legal sense.
It was entrapment because federal agents posing as crime bosses were threatening Ross that if he didn't hire the hitman there would be serious consequences. He was manipulated and forced into the position he was in.
