Training an ML model is very easy. You can learn to pass things through an sklearn decision tree model over a couple hours.

Interpreting it is a more battle hardened task. Don't blindly trust such tools.

KNIME is a free, fairly well used tool in some sectors, for doing low and no-code analysis and machine learning models.

This one perhaps [1]? I only tried it for ten minutes but it seemed nice.
