You still have a receptacle outlet. The LED wallplate is really no different than a plug-in LED nightlight; they arent hardwired. It isnt a luminaire any more than the LED indicators on GFCI receptacles are 'luminaires'.
I agree with this- this is more plug and play than anything else. The only difference betwixt it and what you mentioned is that screw.
Now onto the bigger questions:
Are those tabs considered an outlet or are the outlet screws the outlet or are the wires connected to the receptacle the outlet.........
Are receptacle terminals listed to be used in this way....
There... that should clear up the confusion
What does the AHJ think?
Ultimately this.
But I cannot see an ahj requiring afci just for this and even if they did, not gonna happen.
OTOH, if someone can sell it and make a little extra money, more power to them.
There certainly is nothing that says they cant do that.
