As far as I remember the only historic use of LLC2 was netbeui
(which I've probably misspelled).
That was really replaced by NetBios of TCP.
So we are in the age of 8-bit ISA ethernet cards that stood no chance
of receiving the 15 back-to-back ethernet frames they issued credit for.
Oh, and another stunningly bad ISA card that sometimes failed to indicate
there was a frame in its rx fifo (for pio reads) until the following
frame arrived (even the fifo byte count was wrong).
I can't remember exactly why that completely broke llc2.
