A quincy gathers reishi and uses his or hers reiatsu to compress and manipulate the reishi to form the bow and arrows. Ichigo zanpakutou fed on his reiatsu compressed it on the sharpest point of the blade and then released it in a linear attack. It was only during bankai that his Getsuga Tenshou acquired hollow traits, just like Ulquiora pointed out when he compared black Getsuga Tenshou with Cero Oscuras.

Don't forget that Isshin also uses Getsuga Tenshou and he doesn't possess any Quincy or Hollow powers (afawk anyway). That means that Ichigo's Getsuga originates from his Shinigami powers and is fundamentally a Zanpakutou technique.

Isshin is also a strange case. Remember that he didn't even used Engetsu shikai or bankai form. He simply used Getsuga Tenshou.

And he was spiritually linked to Masaki that was a quincy with the power of a hollow sealed inside her, there's no telling what effects that could've had on him.

At this point it's all pretty much speculation. Which is sad actually. Kubo should've already answered all this questions and more. And not simply leave it hanging. Ichigo technically also used getsuga tenshou without a shikai. Remeber in the Substitute arc when Ichigo and Uryu were fighting a Menos Grande and Ichigo used a blue energy wave in order to take it out
