The tiny entry for Madara's Sage Art Storm Release says he's able to use it thanks to the "power of the Six Paths." It's listed as Senjutsu, not a Kekkei Genkai. I can't read the details on his Sage Art Yin Release attack.

Kaguya's hair needle attack is actually a Kekkei Mora called. I can't read the description due to it being on the crease.

Roshi's Lava Release is listed as a Kekkei Genkai. "It's a technique of Four Tails' original Jinchuriki, Roshi." = 四尾の元人柱力・老紫の術だ.

Naruto's is not named "Sage Art: Boil Release Unrivaled Strength," and is listed as a kekkei genkai. It says he raises his chakra to the boiling point to instantly increase his strength with this Boil Release technique. With the help of Five Tails, Kokuo, he is able to dissolve the ice he's trapped in.

I'm gonna go ahead and stop to post, because that seems to confirm that the those Biju-powered advanced natures are technically kekkei genkai, and the reason Naruto is listed as a kekkei genkai user. I'm also going to note that it specifies that it's accomplished with Kokuo's help.
