Her paying isn't any kind of issue. It's how she went about it. She jumps in and "takes charge" because she starts feeling embarassment in the moment. Jazz is now made to look like a chump because she doesn't want the icky feelings, NFL dude can buy her billboards, she's a boss chick influencer wkith "friends" who are always there to life her up and tell her girrrrrrllll you don't need him the bag is RIGHT THERE, her daddy says it's okay to chase said bag so it's all good, yaaaaayyy girl power. Chick is the ultimate birdbrain but gets constant passes.
It's part of a larger overarching theme in this show but...assimilation games.
