Minecraft allows you to deal critical hits to Squids. You cannot visually deal critical hits to glowsquid.
However, you still deal critical hit damage even when the client does not show. (No noises or particles.)

Every attack dealt to glow squid appears as a "Weak Attack" but deals the correct amount of damage. This same idea also applies with a "Strong Attack". No sound will be produced for this but the glow squid still takes the correct amount of damage.
I've created a separate report for strongly attacking a glow squid as this is different to critically attacking one. This can be found in MC-212594.
Can confirm
