ELI5: Since the president of Comcast said, "We don't enforce data caps." publicly and there is proof that they do, why couldn't a civilian sue them?

"Suing" isn't that simple in American common law. Strictly based on what a Comcast executive said according to your post and not in regards to any other business practices of the company, no civilian would perceivably have legal standing in court.

The first hurdle of holding legal standing (even in class actions if you were involving Comcast and not just the President) is injury-in-fact: that the plaintiff suffered or will suffer actual and particular injury (financial, physical, etc.). There are two more hurdles in proving legal standing, neither of which are relevant because a case based purely on this information would not make it past the first step.

Again, this is in regards to the information of your post and exclusively that. Other factors and information regarding the business practices of Comcast and their executives' actions and legal responsibilities would of course change the situation.
