San Pedro root rot... still usable?

I came home to my San Pedro drooping over the side of the pot they were in. There were about 4 of them (all about 1 foot tall, but fairly skinny). I was going to throw them away, but was wondering, if I dry them out, would they be safe to use?

Only use if the flesh is still firm. Any mushy material should probably be discarded.

Yes cut all mushy parts away and take health parts.
I have save trichos from root rot and sometimes after cut there have left very minimal amount of rotted flesh to bottom of the cactus and it's healed on it's own. Also I have saved one cactus from minor base rot by let it dehydrated for good, if rot is not spread too much there is possibility to save cactus by holding watering and cactus own immunity system get rid of rot. Anyway just cut and discard all mushy rotten flesh with sterile knife and take healthy top part(s) to cutting(s)

Did they get frozen or did overwatering or fungi/bacteria start the rotting? If the cact is frozen it could still be used for tea or extracting if it frozen very recently.

Prevention is key to preventing such catastrophes. Bark chips are commonly used in soil mixes and are a large contributing factor to many cases of root affecting fungus. Well composted leaves and wood are ok but these bark chips (often pine bark chips) should be avoided in your cactus soil mixes if possible. As others have said above you need to remove any "mushy" portions of your cacti. Do this with a sterilized sharp knife. I often rinse the wound with peroxide as an added protection. Then let the plants dry and heal. It is important to really let these plants heal for a long time. I usually wait until I think they are well healed and then wait some more. I have have had some success saving root rotted cacti doing this. Good luck.

Basically it all depends on species or how serious root rot is.
I have saved lots of trichocereus from root rot by let them be without water and stay long time in dry or possible without soil to help roots dry faster.
Some timesn when I remove cacti from pot, I remove bad roots and dry it and plant cactus back so cacti own immune system do the job and heal from rot. Sometimes it's not enough and I need to make a cutting from base or root rot cacti but I have seen also trichocereus and lophophora they cover from minor rot by themselves but they doesn't tolerate any water.
I have rescue lots of trichocereus by take them away from pot and let it dry and I see does it recover on it's own from base or root rot. Trichocereus are very impressive with their resistance to water and possible root or base rot.

I never left, they were lopped over before I noticed anything was ever wrong with them.

it's been starting to get cold, below freezing some mornings. Maybe that did it?

Probably too moist and packed soil with cold air has caused rot.
Just cut the healthy parts and discard mushy parts from plants.
