No, all the URLs you can find in avrdude.conf refer to FT2232C/D
devices.

I think the description in avrdude.conf simply has confused ACBUS and
ADBUS: the MPSSE signals are ADBUS[0:3], see table 3.5.5 in the
FT2232D datasheet.

Nope, the LEDs would have to be attached to ADBUS[4:7] which are
GPIOL[0:3] in MPSSE mode.
