Blight resistant tomato plants

You may have more than one thing going on there but I still don't see anything that can be identified clearly as Late Blight.
I agree with Linda that the damage to the Black Krim foliage does look like Russet Mites. Insects are the first culprits I look for when I see leaf problems. Have you a strong magnifier (10X or better) to look at the undersides of the leaves for mites? Chewing and sucking insects can be vectors for diseases too which just adds to your problems.

You've been picking Krim's all along that are disease free?
The least resistant part of the plant, including Late Blight resistant varieties is the fruit.

From what I've read about Legend, it has no resistance to anything other than Late Blight US8 & US11. So if you don't have Late Blight, why they haven't shown any symptoms to whatever is weird.
