My home field, Oakland (KOAK), is quite a bit smaller than DFW but it
has two completely separate towers...

Interesting...

Do you know why? Is there a terrain feature that prevents one tower
from seeing the whole field? Are the towers short?

Some very large Bravo airports here in the east only have one tower,
as the only folks who need to be in the cab are the controllers who
need to physically see the field. Everyone else (approach / departure
/ enroute, FSS, etc...) can be in the basement or even a different
building.
At Beaumont (Jefferson County) airport Beaumont approach and departure
are in the tower but not in the Cab (the glass enclosure for the
airport controller) The approach and departure controller sit in a
windowless room on the second floor of the tower.

DFW is sprawling. Your options are to make the tower way tall, and
way big so you can fit all the controllers in it such that they can
see everything, or you can distribute things.

When Dulles's new 300+ foot tower becomes operational, it will have
three sets of local (tower) and ground controllers working in it as
well as clearance delivery and supervisory positions. That will
be in addition to the existing ramp tower which controls traffic
pretty much between the terminals and the one on the Udvar-Hazy
tower which serves no useful function other than being a great place
to watch arrivals (now if I could just get them to put real ATC
audio and maybe a live radar feed, the exhibit has a prerecorded
one from EWR of all places).

At Dulles, the radar room for Dulles Approach was one floor down from
the cab (the strips just fall a short distance). At DCA, the new tower
had the radar room in the basement. The tube for the strips actually
fell 12 stories or whatever. Periodically you call the elevator and
find a bucket of strip holders in it that are being returned to the cab.

Now both approach controls along with the ones for BWI, ADW, and RIC
(none of which I've been in) are out at the fringe of the class B
at Vint Hill (Potomac Approach). I asked one of the controllers
how hard you have to throw the strips to jump the intervening 20
miles.

The new Dulles tower does have central VAC.

JFK lists the single tower as 338, and the ground is ~ 12 MSL, so that
tower will be similar.
