Generally, everything physical is a skill, and everything magical is a spell.

Useful silenceable things:

Chimera's Dragon Voice
AK trash cultist's summon.
AK first boss Void Lightning III, Mind Blast, Cripple (forgot actual name, its the heavy afflict).
Garuda's Slipstream

Things you wish you could silence, but can't
AK first boss cultist summoning actual boss
Any Titan ability
You can't silence AK trash summons.
