In California many baby lettuce are grown organic but, since the organic market is a limited market, the lettuce is also sold under a non-organic name. I used to have the list of Co. that were organic but were sold as non-organic. However I have not brought bagged lettuce in years, I tried to find the list but was not to successful(there is a reason it is confidential). There are other produce grown organic but sold under a non-organic label. I wish you luck in finding witch ones they are.
