I know CFIT means "Controlled Flight Into Terrain", but does an obstacle
such as a radio tower count as "terrain"? My guess is that it doesn't, but
I can't find anything that says authoritatively one way or the other.


Yes.

From AC 61-134 General Aviation Controlled Flight Into Terrain
Awareness:

Controlled Flight into Terrain (CFIT). CFIT occurs when an airworthy
aircraft is flown, under the control of a qualified pilot, into
terrain (water or obstacles) with inadequate awareness on the part of
the pilot of the impending collision.
