You appear to have a simulink model named stepinfo somewhere on your path that is interfering with calling the Control Systems Toolbox stepinfo() functions.
I do not find any simulink model named stepinfo in my R2019a installation. Also, the GSCreatingModelsDT.mlx example does not have any invocation of Simulink, and does not create any variable named simout
You should check
which -all stepinfo
to try to figure out where the stepinfo model is coming from.

Execute the command
which -all stepinfo
You will find a stepinfo SIMULINK model listed (otherwise you would not be getting the error message that you are getting). Delete or rename that SIMULINK model.
It is normal for the command to list two .m functions for stepinfo, in
toolbox/shared/controllib/engine/stepinfo.m
toolbox/control/ctrlanalysis/@DynamicSystem/stepinfo.m
but on your system there will be a third entry that names a simulink .mdl or .slx file; that .mdl or .slx is interfering with your code.

The original question appears to be solved then, and it is not at all clear to me what your current question is?
I would suggest opening a new question.
I am not experienced in control system use of Simulink, so I will probably not be able to answer
