If you turn off the output of a LP2951-33 LDO using the SHUTDOWN input, should the ERROR output go LO?

Kevin,

Shutdown just kills the output, the rest of the device is still running. See LP2951-N data sheet for a device schematic.
I just tried it in the lab and error output does sink current. (goes LO)
