I found a partial answer to this myself - it appears that the
TLIApplication class does not support IDispatch, even though its main
interface derives from IDispatch! I determined this when I got the same
error creating the object from C++. This looks like an egregious error
to me!

There's still the question of how this works in VB. Maybe they're doing
something "questionable" under the hood that allows this to work.

I'm still interested in a Python-only solution to this. My workaround
has been to write a C++ COM component that creates the object for me
and does the work for me (although VB would've worked as well).
