Well Camilie is a formidable opponent. However, not the first Jhin has faced. Shen and Zed are BOTH chassing him. I'd at most say Camile is smarter and more skilled than one of them. I think saying that she is more tallented than two people who have litterally been raised fighting and training is a bit much. She's very experienced, but Shen and Zed aren't exactly spring chickens. And when dealing with Shen and Zed, he expressed not wanting to be caught, since it would represent the end of his "art".
He also showed that he knew that she was comming, with Traps already set and priming throughout the building. He also shows he knew the way Camile would move given prompting, in that he primed the chandelleer with explosizes as well. Who else would those be set for? I really doubt he set explosives on the ceiling if he didn't know who she was or how she would act.
So he litterally knew every action from start to finish. Odds of him actually being caught? Very unlikely.
