LH.com allowed me to assign seats on OS flights with LH flight numbers but I cannot assign seats on OS flights with OS flight numbers. The reservations for which I cannot reserve seats are actually in a higher booking class.

I can report back on what actually happened on OS segments with OS flight numbers.
I believe OS OLCI starts 48 hours before departure. I could check in for my flights but still couldn't assign seats. The first leg was on LH so I tried OLCI on LH.com (usually possible without having to wait until T-23) but still couldn't assign seats on OS flights.
Then I received my 'ready for check-in' email from LH, followed the link and was able to assign seats on OS flights (or change pre-assigned seats which I could not see before).
