Then why did Jet Blue fly around for 3 hours burning fuel before
landing back in LAX? It seems like if there is a real reason to want to
burn off fuel there would be a real way to get rid of the fuel.

The prime objective of the three-hour fly-around was not to burn off fuel.
The time was used consulting with engineering to make sure all alternatives
and technical sources had been considered before committing to a compromised
landing. Having said that, burning off the fuel didn't hurt. While a
reduced landing weight wasn't technically required, it was still more
desirable than a heavier landing weight in the instance.
