Lisp was popular for symbolic AI because it has language features (notably symbols) that make it particularly suitable for it. This is not the case for Python for machine learning, which does not have anything that would make machine learning particularly suitable for it. In fact, if machine learning workloads were written in pure Python, they would have been a disaster as Python is extremely slow and these workloads are very computation heavy. Python became so strongly associated with machine learning because the popular early frameworks and libraries were written for it, and they were written for it because Python was and still is a popular language. If some Lisp was popular at the time there's no reason it couldn't have become the language of machine learning.
