For the purpose of LGPL compliance, the source code to all LGPL software we depend on is either in the Ren'Py package (available from Renpy.org), or in the renpy-deps package (http://www.renpy.org/dl/lgpl/). We believe compliance can be achieved by including a copy of this license with every copy of Ren'Py you distribute, and referring to it in your project's README file.
The default Ren'Py build distributes Ren'Py alongside jEdit, which is licensed under the GNU GPL. The source code to jEdit is distributed as part of the renpy-deps package (http://www.renpy.org/dl/lgpl/)
