From Wall of Force:
The caster can form the wall into a flat, vertical plane whose area is up to one 10-foot square per level. The wall must be continuous and unbroken when formed. If its surface is broken by any object or creature, the spell fails.
Does this allow or disallow making a shape (such as a square or rectangle) relative to looking down? For example, could a (typical) large creature be surrounded by four 10x10ft squares of this spell in a single cast?

No, Wall of Force creates a single wall
The spell effect and spell description speak on the singular, a wall.
If the wall could be split into sections, it would now be multiple walls. A common house room has at four walls, for instance.
There are two spell levels of difference between Wall of Force and Forcecage, which does exactly a small room made out of walls of force. It wouldn't make sense for Forcecage to exist if Wall of Force could be shaped and create an effect similar to Forcecage.
Look at one of the effects of Forcecage:
