There are still marked crosswalks in the UK, though, correct? (The only part of the UK I've been in is London and that was years ago, but I remember seeing marked crosswalks and people generally keeping to them when crossing and obeying traffic signals.) Does the presumption that the driver is at fault depend on whether the pedestrian is in a crosswalk or not?

There are a few for the busy roads, but there are many, many smaller roads with unmarked crossings. In the countryside this is the norm and pedestrians and hikers walk along the road as well.

We even have a few national trails go straight across motorways without crossings!

No. You can use a crosswalk or ignore it as you like. Of course most people use them cause they prefer not to get hit by cars.
