Use JS tone generator as your LFO, follow it by a simple JS that assigns incoming sample values to a slider, link that slider to whichever parameter you actually want to modulate. Then you can modulate or automate the frequency slider in the tone generator.

You might also check out some of the JS ReaRack modular synth stuff in the stash. It has LFO modules that both send and receive either MIDI CCs (which can be used in PM for plugs that don't directly support such things) or audio-type "control voltage".
