You could try to override the shape of the slur so that it no longer
collides.  Example:

    | <c a>2.
      \shape #'((0 . 0) (0 . -.75) (0 . -.75) (0 . 0)) Tie
      a~ | a4

Replace Tie with PhrasingSlur, or other such curved object in question.
Experiment with different values to the \shape command until you find
something that works for you.
