Yep, that's true.

Tonberry's have high defense and HP, so it's difficult to wear them down and KO the before getting hit with too many Everyone's Grudge attacks as a counter, and possibly getting knifed. This is especially evident when you have to kill 20 of them in this manner.

That's why I recommend having a hasted Squall use a couple Renzokukens. If he gets hit by Everyone's Grudge, it would have killed him anyway, and he should be able to pull off two (shouldn't take more than one or two) Renzokukens without interruption. If he does get hit, a Phoenix Down will suffice.
