You were right, I didn't wait long enough. (I didn't know about the
"every 30 seconds"). But I tried again and I never saw them with -D in,
and with -D out I saw the one from OpenBSD.

You were right again. As I didn't see the LACP packets, I looked more
carefully and yeah it appeared it was not configured as a LACP trunk. I
deleted the trunk and recreated it (it was immutable) and now aggr0 is
active. Yay!
I thought that since trunk0 in lacp mode was working, it meant the
switch was correctly configured.
Out of curiosity, I tried the commands from sthen, and indeed now they
show something:
TL-SG3216#show lacp internal
Flags: S - Device is requesting Slow LACPDUs
F - Device is requesting Fast LACPDUs
A - Device is in active mode P - Device is in passive mode
