GENERAL

Your cause is good. But mobile phones under low cost are out there e.g. Intex, spice etc.
Also there are apps to make the user interface of android so simple, one of them I know is
Wiser.

Don’t go for hardware development side if you just want interface to look simple. And if you want to build low cost thing device the manufacturing, microprocessor, display, frame etc will go above 45$ at which a fine working android phone could be bought.

Move forward, build better!

You are right about android phones. But it’s not a smartphone. It will not have any other function. It’s only function is to video calling and senior citizen monitoring. secondary we will learn implementation of video calling api on Rpi. That can be used in future developments. We can’t use smartphones everywhere just because they are cheap. E.g. If I’m making a robot and wana add video and audio feed to it, plus control it via internet. Then using android device will not be sufficient. While with Rpi or any other open source hardware it will be very easy to customise it.
