I have TeXLive 2016 on a Debian 9.1 system. It seems to default to A4 paper size, and I'd like to change it to letter. I tried
tlmgr paper letter
but I get
(running on Debian, switching to user mode!)
tlmgr: action `paper' not supported in usermode
tlmgr: An error has occurred. See above messages. Exiting.
I don't see any option to run tlmgr not in user mode, so is there some other way to let pdftex know that I want to use letter paper by default?

You are using
tlmgr
as shipped with Debian. In Debiantlmgr
always runs in user mode as clearly indicated in the output.Configuration of the TeX Live system on Debian is different from how it is done in upstream, because TeX Live has to integrate into the Debian framework.
That means, for paper configuration you need to use
paperconfig
command (as root).
