Solar systems have dynamics similar to galaxies. There are many elliptical galaxies. Are there solar systems which maintain several substantially oblique (or perhaps "random") planetary orbits?

Our own solar system has many comets with highly elliptical orbits.

But they are mostly (more or less) in the plane of the system, aren't they? I think the question is not so much about eccentricity of orbit as the angle to the plane of the system.

The chaotic satellites might allow extreme ellipses, but not much in the way of skews from the orbital plane (averaged out over many bodies in galaxies)?

Turns out that some of our sun's comets approach from random angles. Quote:

Does the threebody approximation approach freedom of rotation in 3d space?
