I also use LIly to print jazz charts (see
http://www.bearteam.org/~laurent/partitions/) and I also encountered a
few problems in the area of chords. I fixed some of them, but some
chords still have strange names. 

Here's what I use :

#(define chord::names-alist-jazz
      (append
      '(
        (((0 . 0) (2 . -1)) . ("m"))

        ;; some fixups -- jcn
        ; major seventh chord = triangle
        (((0 . 0) (2 . 0) (4 . 0) (6 . 0)) .  ("$^\\Delta$"))
        (((0 . 0) (2 . -1) (4 . 0) (6 . -1)) .  (("$-$")))
        (((0 . 0) (2 . -1) (4 . 0) (5 . 0)) .  (("$-$6")))
        (((0 . 0) (2 . 0) (4 . 0) (6 . -1) (1 . -1)) .  ("7"
                                ((raise . 0.8) ((font-relative-size . -2)(music 
(named ("accidentals--1")))) "9")))
        (((0 . 0) (2 . 0) (4 . 0) (6 . -1) (1 . 1)) .  ("7" ((raise . 0.8) 
"+9")))
        (((0 . 0) (2 . 0) (6 . -1) (3 . 1)) .  ("7" ((raise . 0.8) "+4")))
        ;; (((0 . 0) (2 . 0) (4 . 0) (6 . 0)) .  (((raise . 0.5)((font-family . 
math) "M"))))

        ;; minor major seventh chord = m triangle
        (((0 . 0) (2 . -1) (4 . 0) (6 . 0)) . (columns ("m") ((raise . 
0.5)((font-family . math) "M"))))
        ;; (((0 . 0) (2 . -1) (4 . 0) (6 . 0)) . (columns ("m") ((raise . 
0.5)((font-family . math) "M"))))
        
        )
      ;; '()))
      chord::names-alist-american))
