If you want nonlinear noise, you need Keysight's Advanced Design System
or such. Be prepared to a 5 or 6 digit price tag, depending on options.
The keyword is harmonic balance simulator.

Nah. The LTspice noise() and white() functions give you time-domain noise,
with uniform or Gaussian amplitude statistics, and are good enough for many
things.
If you want separate voltage and current noise contributions, you can use a
voltage controlled current source.
To keep the complexity down, you need to do a little analysis to figure out
what the dominant noise sources are going to be, so that you can just model
those.
