It did look like the tip of Yhwach's spirit weapon pierced Ichigo's skin, but that was the very first time he used his Blut Vene (although unconsciously) after Kirge's jail awakened his Quincy powers. I dunno if that could have something to say.

But I wonder - it's been stated that all Echt Quincies can use Blut from their birth, without any training, and it's been implied that Ichigo is an Echt Quincy like Masaki was. Does this mean that now that his Quincy powers are awakened, his Blut Vene will protect him without him even being aware of or conscious about it, like it did the first time mentioned above?

I personally see the answer to that question as yes.
