That is, if you imagine all that mass-energy springing into existence in a vast universe (but with every point much closer to each other than today), there was not enough time for all that energy to notice the gravity of the surrounding mass-energy density and collapse into a black hole. Add to that the expansion rate (inflation), and the extreme uniformity of the young universe (which means gravity would have been pulling every thing in all directions rather than "inward" towards a soon-to-be-black-hole-center), and a collapse was impossible.

You can't; this violates conservation laws. In other words, there is no solution of the equations of GR that describes mass-energy springing into existence in a universe that was empty up to that point.
At the end of inflation, matter and radiation in the form we know them today (the quantum fields described by the Standard Model of particle physics) got a huge amount of energy pumped into them; but that energy did not come from nowhere. It came from the inflaton field--the field that caused inflation up until that point--so that energy was already there and there had already been plenty of time for its gravitational effect to be "noticed".
