You need a subpanel to break out the inverter items.

I don't understand, I don't want it to backfeed the main panel, that's the whole idea of not feeding the main panel with the ats. I just want to run one dual breaker off the ats output. Do I really need a whole subpanel for one breaker?

a box with one or two circuit breakers
can be a sub panel or a switch box, depending on how its wired
coming from the ats to a dedicated circuit Not powered by anything else
it is both a switch box and protected circuit at the same time

a sub-panel in RV context with a generator, shore, and inverter
is s selection of one or more circuts that can be powered by shore/gnerater switched by main ats,
and also powered by just the inverter
in other words that panel has multiple possible power sources
it isolates circuits that will be powered by inverter when other circuits do not have power

for safety things have to wired where there is absolutely no possibly of two power sources being connected to the same circuit
a sub-panel with mechanical interlock allowing only ONE choice, either/or is the safetest way of doing this

an ats choosing between two sources ( the oem breaker panel and the inverter ) can be used, as long as there is a CB between the output and the circuit

i have an ats on my fridge circuit, so it switches to a circuit from the breaker panel when the generator comes on

wiring can get confusing
and sometimes, its not clear what somebody is trying to describe
