Don't know abou Yoders but Tommy Toes I'm pretty sure are currant/wild type. I see in your photos leaves with rounded edges which are typical of this type.
I generally don't worry about leaves lower down because they get shed by the plant as it grows or I will bury them when uppotting. If the purple was due to too cold temp, the recovering leaves will look ragged and not as healthy as upper leaves, but I wouldn't worry about them. I do clip off the lower leaves that are touching the ground when they are planted out.
For now, the seedlings need whatever energy production they can get out of their leaves, so I would only clip them off if the damage and stress outweigh the benefit. Stressed plant will be more attractive to pests and diseases.
If the lower leaves are not getting enough light, they will yellow and be aborted by the plants.
