Is there just a trig point here or is this really the name of the hill?

This is a major misuse of highway= pedestrian tag
Please desist and refer to wiki
A highway=pedestrian is a road or an area mainly or exclusively for pedestrians in which some vehicle traffic may be authorized (e.g. emergency, taxi, delivery, ...). Typically found in shopping areas, town centres, places with tourism attractions and recreation/civic areas, where wide expanses of hard surface are provided for pedestrians to walk.

See if this needs an update

OS Locator suggests this section of Bristol Road South is called White Hill.
