I still have my training wheels on, but I am trying to model the subject
antenna, as described in the ARRL's Antenna Classics.

The feed end at ground level calls for a 9:1 transformer. The opposite end
(also at ground level)calls for a 9:1 transformer with a 50 ohm dummy load
attached. How would I include these in the model?

I would include a one-segment wire at each end to hold the source and
load. Use a 450 ohm load and set the alternate SWR Z to 450 if you
want to see the SWR normalized to that value.

This assumes that the 9:1 transformers don't add any reactive effects,
something you can't know anyway without some measurement
characterization.
