*ALL* low temperature JEDEC bakeout profiles require controlled humidity, under a fairly low threshold, (IIRC, 5%).
The RH in a vented hot oven will be much lower than ambient, and if you know the ambient RH and the ambient and oven temperatures, the oven RH can be calculated so long as the chips don't contribute significantly to it (large oven, few chips). If the ambient RH is fairly low (e.g. a dry room with a full sized dehumidifier running in it), you probably wont need quicklime in a vented oven, even for sub-100 deg C bakeout profiles, provided some air can flow in slowly at the bottom to let hot humid air escape from the vent.
Whether or not exceeding 100 dec C is damaging depends on the size of the voids in the IC package and how much you exceeded 100 deg C by. You won't know till you try to use the chips whether or not you damaged them, or even if they were bad to start with which is quite probable if they were used parts desoldered over a charcoal brazier, washed in the river and dried on the pavement! Depending on the relative value of the chip and assembled PCB, the difficulty of testing, and the difficulty of rework, it may or may not be worth trying to use them if the boards are for yourself, but if you are planning to sell them, you definitely need to find a better supplier.
