In literary terms: Is the Original Hebrew Bible completely irrelevant to the western canon?

There's this discourse going around circles that study literature under what I can only call "the theory of influence," which expounds that the Holy Bible, alongside Plato's writings and the Odyssey/Illiad are the most influential and foundational texts in Western history. Critiques to this view aside, and giving into the merits of this way of thinking: wouldn't this make the original Hebrew Bible almost completely irrelevant to Western literature?

The Latin Vulgate inspired Dante's master work and the English King James Bible can be argued to be the main source from which John Milton pulled to write his Paradise Lost. I'm not well versed in Eastern European literature, but it's fair to suspect that the Greek Nikos Kazantzakis, pulled from the Koiné Septuagint and New Testament to write The Last Temptation of Christ (given that Greeks usually read in the original), and that other Eastern authors either pulled from their regional translations, the Vulgate or from the Koiné as well.

If this is truly the case, has the original Hebrew Old Testament had any merit in the Western literary world beyond providing the base text for translation?
