This is how St. Paul describes these "all" (Romans 3):

This is WHO the all is:
Rom 3:9 What then? Are we better than they? Not at all; for we have already charged that both Jews and Greeks are all under sin;

If you don't fit in one of those two category then you're OK. (Note: not to pick on our Greek friends but Paul used Greek and Gentile interchangably) We were/are ALL like this. It is only because of God's mercy that He has saved us out of this condition. Not that I'm criticizing you but if you don't see yourself in this list then I would suggest a closer examination.

I know how deeply the late Reformed hate the Mother of God

Yes, yes, I know. Vile, aren't we? That fact that we say Mary was just like the rest of us, a weak and fragil creature in need of God's grace and mercy as is documented in scripture is just another form of hate speech.

ALL WE like sheep have gone astray...

There is a continuing flow of thought from verse 9 to 11-16, and no, 11-16 does not apply to Our Lady.
