I couldn't find any utility on the FTDI site that will safely indicate if
you have a fake FTDI device.

That may be true of Prolific chips.  But FTDI chips are actually killed and
rendered useless according to multiple sources.

Which confirms the same thing at the bottom:  "current update of FTDI
drivers in windows made things much worse: software-compatible chips
abusing "FTDI" marking are now silently bricked by FTDI drivers by
resetting their PID."

"Bricked" or "to brick" is jargon/slang for "cause (a smartphone or other
electronic device) to become completely unable to function, typically on a
permanent basis," as useful as a brick of clay.
