When it is added in kits before fermentation it is just stirred in. Is this
just because if added during fermentation, the yeast action stirs it up so
you do not have to boil it?

I never heard that it has to be boiled, the only fining agent that I
know has to be boiled is hot-mix Sparkalloid... There are different
types of bentonite out there, so their preparation might differ. The
one I'm using after ferment just needs to soak in water for 24 hrs or
so - I'm using hot water but that's just because it makes it easier to
make the slurry that way.
