Ciao! I wouldn´t worry too much, since at the end, the skillset tested is the same than in the "usual" cases, hence, all the practice you may have done totally plays in your favor.
Hence, even if the italian companyyou are interviewing for has them, they will let u know in advance, and you will levearge all the work you have done with normal cases
One important point to add is the need to be very 80-20, structured and to the point, since the prep time is very short, so we need discipline with the analysis to have enaugh time to prep the communication strategy.
There are many many entries in thsi same Q&A regarding written cases, hence, I would recommend you to look with the keywords "written case"
Hope it helps!
