Strasser is actively trying to prevent that from happening (Antagonist). Once Lazlo gets those letters, the problems in the story are resolved and the film is over.
Here's the problem:
Laszlo's story involves much more than the letters of transit. He's not in Casablanca because of the Letters of Transit. He's not even initially in Rick's cafe because of the LoTs.
The story is about how the LoTs intersect with, and mix up, RICK's life, not Laszlo's. This is actually probably the least cinematically interesting bit of Laszlo's journey to freedom, if you think about it.
