Wouldn't matter "how old" the lecturer is. There are younger people who would probably do the same thing and are luddites. I have one friend who refuses to get a smart phone. Am sure there are others who avoid technology in general too who are anywhere between the ages of 18 and 100.
No idea how I can help but surprised they say that you should have requested at the beginning of the term. Standard I guess but I would think they could find an interpreter with 2 weeks notice. I don't know when your term ends so that may be another factor (in the US most universities/colleges end the semester around May).
