In the UK we have a good setup where is a pedestrian walks out it's on the driver to be careful and try stop, therefore the presumption is normally that the driver (or larger vehicle generally so lorry>car>cyclist>pedestrian) is at fault in most cases. It sounds chaotic but in practicality it's balanced by the fact most people don't want to be hit by a car and we teach kids from a young age how to cross roads.

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.
