The wikipedia page doesn't say much about Pu-238, but there is this under the "Proliferation resistance" bullet:
"...LFTRs produce very little plutonium, around 15 kg per gigawatt-year of electricity (this is the output of a single large reactor over a year). This plutonium is also mostly Pu-238..."

In a LFTR the fuels are dissolved in liquid salts, so the downside is it may be very difficult to separate out the Pu-238 for use.
