Thank you for your interest in Raspberry Pi.
We cannot provide legal advice, but our understanding is that it is legal to distribute the Raspbian image as-is. Note that special terms apply to the use of Java in "non-general purpose compute" platforms such as kiosks; we do not believe this applies in this case.

Anything from Debian main should be legal to distribute as long as you also distribute the source packages.
Since you are using a Debian derivative and not using Debian, you'll need to review the parts that have been added to or changed from Debian. The Raspbian people can probably tell you about their policies but I imagine that Raspbian main has the same policy as Debian main.
So you should check if any packages not from Raspbian main are installed and review their copyright information.
To make things more complicated, as I understand it, the Raspbian images distributed by Raspberry Pi are modified from the Rasbian distributed by Rasbian themselves. I personally don't know what changes were made, hopefully the Raspberry Pi folks will answer you.
