AA is irrelevant. Artillery spotting generally require 2x gun 1x seaplane recon (or bomber), and is enabled if you have air superiority. Any setup without seaplane recon/bomber (or 2x gun) is non-artillery spotting setup.

If you don't have air superiority (enough fighter planes) then artillery spotting setups are wasted - they won't activate anyway. But note that 2x guns are often still preferred (for yasen) and seaplanes might be still useful for LoS requirement purposes.
