Many Torellis were built by Mondonico and imported to the USA as unpainted frames for final paint and prep. This looks like a late '80s "budget" model (based on tre-tubi Aelle frame) so probably not built by Mondo (but not certain either way). It's NOT junk, just made to offer quality at a lower price point. I bet it rides just fine, most Torellis do, so ride and enjoy it. DON'T do anything surgical to the frame if you ever want to return it to multi-speed, for yourself or another.
