Ok, so I can confirm that once I create /dev/ttyO2, I see the text I'm sending to plymouth appear on my serial console

Is there a way to override this behavior, so that I can test plymouth without sacrificing my (only) debugging interface?

plymouth forces text output if there's a serial console attached.  You
have console=ttyO2 on the kernel command line so that's what it's
doing.

This confirms it here ^

You also don't have the /dev/ttyO2 device node created, so it can't use it.
