And a LFTR doesn't make Plutonium, present reactors do.
However, a LFTR does make U233, and more that it needs to keep functioning by about 8%. Operating as designed this is contaminated with U232 which makes it unsuitable for a bomb. But if the operators skim out Pa233, which is the precusor to U233, and then let it beta decay to U233 it's not contaminated by U232 and is usable for a bomb. It's harder to make bomb from U233 because it's critical mass is about half again that of plutonium but it has been done.
So LFTRs are better than uranium based power plants, but you would still want an inspection regimen in place to prevent proliferation.
