I guess dict1's values can also be dicts, lists, etc.

Have you considered using codeop.py to attempt to compile their Python
list and dict code?  If you're wary of them doing unwanted stuff in the
code they provide then maybe opcode.py can then be used to scan through
the compiled bytecode to check they're just doing simple dict and list
construction?

Cheers,
