The FTDI chips are significantly more expensive than the PL2303, so you will
not commonly find them in consumer electronics.

As the T191 cables are intended for low / standard baudrate applications,
I would be _Extremely_ surprised if you ever find a cable with the proper
2.5mm plug that has a FTDI chip.

Better to build one yourself, or buy one of the FTDI cables from their webshop
and solder your own 2.5mm plug to it.
