It makes some sense to make a dash to the west by Piccadilly line, perhaps
transferring to a main line train on the outskirts.

But in what scenario might this option be any better than a road or air
evacuation, or staying out? I can't imagine one.

It would probably be more secret. And it depends what the risk is. If it
was a dirty biological bomb in London, and a riot amongst the populace
who were being prevented from leaving for fear of infecting the rest of
the country, it could well be the best of the three options.
