I didn't read anything but the first post. NL is very stable and a (almost?) pure indica. Indicas have a much lower likelihood of turning into hermaphrodites than sativas.
If the "hermie" is a result of stress, then the resulting seeds are feminized. They will be just as likely to "hermie" as the parents, which was most likely due to stress, not so much genetics.
This is most likely.
If the plant was not stressed and turned "hermie" by it self, then the resulting seeds will be a mix of male, female or hermaphrodite.
This is very unlikely.
I keep hearing people talk about hermaphrodites that do not recognize there is more than one type of hermaphrodite.
If a plant grows without stress and then shows both sex organs, the plant has a Y chromosome and is a hermaphrodite that can produce seeds on itself and other plants that could be male, female or hermaphrodite. If a female plant grows, then becomes stressed by the growing environment (temp/temps swings/humidity/poor nutrients/poor nutrient ratios...) that female plant will not have a Y chromosome. It will have a XX chromosome. If the pollen from that female plant produces seeds, those will be feminized seeds. They will be just as likely to "herm" as the parents.
There are plants/varieties that are more susceptible to stress, making them more likely to "hermie."
I have produced feminized seeds. I am basing this on experience and research.
