I'm assuming the list of throw-exploiting-assassins is basically Tiiga, Jeede, Nazaretes, Cainasir and Qinsa, all of whom died in 2016, and all of whom except Jeede had Master of Nage Waza.

I sorted by PKW and then went from the top down and picked out characters that died in 2016. Many of these have detect hidden, and some of them would have been allies of some (but not all) of the above assassins. Here's what I've got:

Reegun, human shaman, 163-53 overall, 1-3 vs. assassin
Others: 0-2 vs. transmuter, 7-7 vs. druid, 2-2 vs. AP

Golthazar, duergar warrior, 158-62 overall, 9-2 vs. assassin
Others: 0-6 vs. transmuter, 8-9 vs. paladin

Kaer, fire warrior, 150-77 overall, 8-7 vs. assassin
Others: 2-3 vs. rangers, 7-14 vs. shaman, 0-1 vs. necromancer

Darvoderis, half-drow shaman, 131-114 overall, 5-16 vs. assassin
Others: 0-2 vs. transmuter, 2-4 vs. thief, 6-8 vs. paladin

Grimghal, duegar warrior, 128-28 overall, 1-1 vs. assassin
Others: 4-4 vs. paladin, 5-4 vs. necromancer

Mhirnal, drow anti-paladin, 118-6 overall, 8-1 vs. assassin
Others: n/a

Zalgordrax, mummy necromancer, 113-16 overall, 4-4 vs. assassin
Others: n/a

Muuksube, duergar shaman, 112-11 overall, 4-1 vs. assassin
Others: n/a

Tsalantha, drow anti-paladin, 174-9 overall, 15-0 vs. assassin
Others: n/a

Out of these nine, five did worse against assassin than their overall record would predict. Though, in some cases we're talking about very small numbers, e.g. Reegun going 2-2. That's worse than his 163-53 record would predict, but when you only die twice to a class over a long life it's hard to argue you were dominated by that class.

Only two, Kaer and Darvoderis, had more than a handful of deaths to assassins. Darvoderis had 114 PK deaths (!!!) so his assassin death count may not mean much. He seemed to die to all kinds of classes.
