This is a legit commercial. I see no reason why you should get paid. However, in my experience in working direct-to-client, you have to submit a form to your PRO. If this was placed by a library, it’s on them to do it. Talk to your PRO and explain how this aired and they will explain if you need to do anything. Hopefully they air it a lot and at prime times. I wrote many seasons for Robot Chicken and they pay very well at Cartoon Net with BMI.
