I was a full-time resident of TX in 2016, but had a one-time paid speaking engagement in Chicago. Do I need to file an IL state tax return?

Yes, If you receive income for speaking engagements conducted out of state, then yes this would be considered working out of state.  

So depending on how much you made at engagement, he may or may not need to file a return for a particular state.
