A twisted hose may be breaking down internally. As to if it would be more noticable that the brakes on that wheel would apply slower or release slower depends on the nature of the restriction. Most certainly, I would replace the hose and see what you have from there.
Basically you fix when you find and go from there. You just complicate things when you have a know problem that you don't fix.
If the hose replacement doesn't resolve the problem, have a good look at the calipers and make sure that the caliper slide pins are properly cleaned and lubricated as well as any part of the pad backing plate that comes into contact with the caliper.
It is also possible that it is suspension related, even with good alignment readings. Have a good look at the lower control arm bushings. Someone recently posted that after going through the brakes thoroughly to resolve the same problem, the problem was finally resolved by replacing the lower control arms
