Clemson defender should have had his hands up trying to deflect the ball - whether Lydon was going to shoot or pass - instead of running up and putting his hands in charge-position. The clock expired when the ball was in the air. Any touch on Lydon's pass and Battle might've run out of time. Either way, to OP's question, on TV it looks close but my orange-colored glasses are inclined to say it was a flop.
Also, if you listen to Matt Park's call at the end of the game, he mentions how Clemson's coach was trying to call a timeout and how it could have been a T.
