liner is indirectly grounded, I guess, via the furnace ground. If TV
antennas need to be grounded should chimney liners be grounded as
well?

Thank you for your thoughts!

Can't hurt.

Put up a lightning rod, which doesn't ground anything, to discourage
lightning in the first place.

If you ground a metal liner you will just attract the lightening,
something you don't want. If lightening will blow the bricks off a
chimney which is not a conductor, I don't think lightening cares where
it strikes. If you ground it and it attracts lightening it could still
blow the top of your chimney off. A higher lightening rod may attract it
instead, (may). It's not an exact science.

Lightening is what Michael Jackson did to his face. Lightning is what
happens when clouds build up dissimilar charges and there is a giant
spark between the clouds or between the coulds and the earth.
