Description
Description
This is an odd output type. Also we could avoid an extra conversion from the Jitted functions, which naturally return tuples, not lists. May count as a breaking change so perhaps for PyTensor v3

Research direction
The issue names no file, function, or test. Start by locating the PyTensor function that returns a list for multiple outputs, compare its result with the jitted function's tuple result, and check how the potential PyTensor v3 breaking change is handled. Done means the multiple-output behavior and its compatibility scope are clearly defined.
