So with Pluto, at approximately 3.3 billion miles from us, Voyager is about 4-1/2 times farther out from Earth than the dwarf. Is there any object closer to 15 billion miles than Pluto?

Yes, including Eris and, I think, four other dwarf planets. This is why Pluto is not considered a planet anymore.
Eris is around twice as far from the sun as Pluto.
Google give: V774104 currently sits 15.4 billion kilometers from the sun, or 103 astronomical units (AU) away.
15.4 billion km equates to 9.57 billion miles.
Everything to the right of the red vertical line labelled "Plutinos" in the following chart:
So: Only a couple of hundred that we know of (i.e., whose orbital data we have already reliably calculated).
Voyager 1 wouldn't even appear in this chart, since it's so far away (far off to the right of where the chart ends).
