Is it possible to set contentDescription or some similar attribute for the whole RecyclerView so that a screen reader app like TalkBack would read this contentDescription when the list is first reached and only then proceed to list items?

When you set the content description for RecyclerView, it will be announced by Talkback. Instead of a generic "In list" announcement, the user will hear "In list ". This can be used as a short description to better explain the purpose of the list, like a name for the list. It will also be used to announce when the user navigates away from the list.
This is not the expected place to put in a longer explanation, as it is used both to enter and leave the list. If you need to add additional information, a better approach would be to have some sort of label before the RecyclerView, so it's available for all users, not just via Talkback.
