Hi Jmax,
In the hagadah we say that the havtacha of yitziyas mitzrayim stands for our fathers and for us, through all generations, to save us from destruction.
On this the hagadah continues, go and learn from Lavan… The pshat I had on this(quite a few years ago) is that the hagadah is darshening the above question of what connection is there between Lavan and Mitzrayim?
The drasha is that the havtacha of vayered mitzrayma saved Yaakov from arami oved avi. This proves v’hi sheamda lavosaynu…
