It seems like it would make sense to leave a gap between each battery module for instance if we look at the Nissan Leaf book like modules we could put an 1/8 of an inch spacer in between them or 1/4" to allow the heat to dissipate essentially making them air cooled

I can think of space as being an issue but wouldn't there be a trade off for cooler battery operating temperature?

Is it to prevent them from bulging?

I'm new to this so please be gentle.

Yup, the "compression" or bolting them together helps to keep 'em in the proper shape & thickness

As an alternative kooling option, I'd thought of installing aluminum sheets in between each module
...but, have them stick out a bit (probably like 1/2" to 1") on each side, essentially adding cooling fins to the pack ;)

That's what typical pouch cell modules have to transfer heat to the thermal management (cooling) plate under the module - in that case, each sheet is bent 90 degrees at the wall of the module to lay flat against the plate. Examples include all of the LG Chem modules without coolant circulating right between the cells: Chevrolet Bolt, Chrysler Pacifica Hybrid, etc.
