Isn't "class A" a way of saying "discrete devices, no ICs"?

No. That's what the marketing people want you to think.

With the right op amp (and a heat sink), you can "pull up" the output stages
into class A.

Some op-amps (like the MC34082) have class A output stages already.
And plenty of discrete stuff uses push-pull stages that aren't worth
bothering to run in class A.
