I understand the error in the OP and I agree with your explanation. It is a common misconception in introductory physics to consider centripetal force as some special force in itself. But any force, either a single force or a resultant can be centripetal. It does not have to be a resultant.
Even thought now I am not sure if the centripetal force that acts on a planet orbiting the star would qualify as applied or resultant. And the same for any other macroscopic force.
And I just don't see how calling it "applied force" make any sense. Especially when the label is "applied" to inertial forces or components of inertial forces which are not applied by anything.
It seems to be more misleading then useful.
