Maybe this code can give some hints on how to decide if midi is being 
produced.

\version "2.20.0"

#(define (outputdeftype def)
  (cond
    ((ly:output-def-lookup def 'is-layout #f) (display "\nlayout"))
    ((ly:output-def-lookup def 'is-midi #f)   (display "\nmidi"))))

\book {
  \score {
    { c'1 }
    \layout{}
    \midi{}
  }

#(for-each
   (lambda (score) (for-each outputdeftype (ly:score-output-defs score)))
   (ly:book-scores $current-book))

}
