Take a look at libpaper and papersize-default-a4
Tha later just create symlink /usr/local/etc/papersize from 
/usr/local/etc/papersize.a4

https://www.freshports.org/print/libpaper/

I tried it now and it works for me. I also had Letter in LibreOffice. 
Now I have A4 as default in LibreOffice with this:

# cat /usr/local/etc/papersize
a4

So thank you for your question, it solved my problem too :)
