That is the point; it is at the discretion of the FFL to take the LTCF as ID, this according to PSP PICS folks.

I spoke with an FFL that I know and he said he would turn it down also. His point is that the PICS is set up for a DL number input, making the call quicker. Apparently, the FFL needs to talk to a live operator to use any other form of ID. Time is money!

The good news is, you can always take your business to another FFL.
