Well, there's always a bright side. :-) Basic Economy is a special class of highly-restricted fare that is currently only available domestically. The terminology is confusing, especially since you were shopping for a route where Basic Economy isn't sold.
This is probably better asked in the TSA forum. I've had no problems bringing solid food through the checkpoint. I don't know whether an icepack would be allowed or not -- I've never tried it.
If on a Basic Economy fare the bag you bring on the plane must fit under the seat - period. Seems the OP is not on a BE fare.
Baggage Fees are not refundable.
I would not try to bring an icepack unless you have a medical need for it (with documentation).
