LilyPond generates separate MIDI tracks, in separate channels, for the two
staves, so as far as anything playing the MIDI file is concerned, it is
not a "louder" note; it is two notes in unison.  Nothing about a standard
MIDI file indicates to the playing software that these two tracks happen
to be the right and left hands on a single instrument.

If you don't want the two notes to play at once, I think what needs to be
changed is the fact that LilyPond is generating separate tracks per stave.
You might be able to use \partcombine to collapse them into a single
track and eliminate unisons.
