1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

Can we get the dihedral coefficient for dihedral_style opls? If not, how do we arrive at it?

Yes, you can use OPLS forcefield, OPLS is the base of all forcefields.

In that link, opls co-efficients are not mentioned. Where do we get the co-efficients?
