Admittedly this may be above my math level, but this just seems like a bad definition of elementary functions, given the context.

I would agree, it makes them anything but elementary. I am honestly not even sure if there is a finite constructible basis of the functions that can express any solution of single-variable integer polynomials.
And for multivariate polynomials, the roots are uncomputable due to MRDP theorem.
