Well, looking at the stats, estimates of the prevalence of personality disorders in the US population run from around 9% to 15%.

By contrast, if the sixteen types are evenly distributed, LSIs would be 6.25% of the population.

Therefore, there's a greater likelihood of meeting someone with a PD than who is LSI. Maybe Kim met an actual personality-disordered person and mistyped him LSI because that's her conflictor.
