JAL is liable to the USA, but not to you. There is no chance that JAL will refund the amount you paid and they might even attempt to get back the money they paid as fine to USCBP.
For the USA, there is no sterile airside transit like in many other countries. Every person transiting has to clear the passport control and customs before catching their onward flights. This probably has something to do with the US policy of not having exit immigration controls.
Regarding penalty, yes. You should have been denied boarding by JAL. Due to their mistake, you are allowed on board. Like every country, the airline will be penalized for allowing you on board. You are just lucky that they didn’t deport you, as is generally the case.
There might be consequences for your future flight with JAL.
