Hm, at least according to Frescobaldi's auto-completion LaissezVibrerTie does *not* have a minimum-length property, which is confirmed by that result ...
Also, \shape does have no effect on the \LaissezVibrer, sorry.
LaissezVibrerTie is an item not a spanner, minimum-length is part of the spanner-interface, thus this item does not react on it.
Though, LaissezVibrerTie has control-points, \shape works for me:
b-\shape #'((0 . 0)(0 . 10)(0 . 10)(0 . 0))\laissezVibrer
