Your lexical research on PASA is admirable, but I suspect that the problem you're having is more
closely related to the word GRAFH. GRAFH, after all, simply means "writing," "text." Thus PASA
GRAFH THEOPNEUSTOS may simply be taken to mean "every inspired writing," obviating some of
your every/all problems and eliminating the need for your question about "uninspired Scriptures."
Yes, of course there are uninspired writings, from bills of lading to casual personal letters.
Grace and peace,
