It's the other way around. They have no levels to interact with something like Counterspell or Globe of Invulnerability. It doesn't need anything explicit saying it doesn't interact any more than an axe does.
Here's a sample - the old Derro Savant had a bunch of spells, including Chromatic Orb. This has less spells, and Chromatic Orb is turned into a attack power Chromatic Beam.
It doesn't even pass the "Is this a spell?" test in the SA Compendium.
An Oath of the Ancients paladin with an aura granting resistance to spell damage won't affect this, though it would for Chromatic Orb. A Globe of Invulnerability, or monster-like equivilents like the Rakshasa's Limited Magic Immunity, don't stop it as written. Heck, there's not even anything that says a resistance to magic would help, though a DM could make a ruling.
