I mean typically the US doesn't airmail dollars to the warzones.

Typically it's a numerical value for the goods & services provided. This means the USG is paying Americans to do stuff for Ukraine which increases demand for US stuff which helps the US economy.

A significant portion of the help wasn't dollars, but obsolete weapons and ammo from the army's stockpiles, that US gave Ukraine instead of basically disposing of it locally.
