A question on a single G5 used as an Attitude Indicator: no other devices are connected to the G5, so is it required to terminate the CAN bus pins at the G5?

No. Even the FAA approved STC install manual shows them open when nothing is connected.

No.
Installed one on my previous aircraft as a standalone unit without any termination... worked perfect.
Loved it so much that I have ordered one for the RV now
