That is not true. The rsyslog.service file in Debian's rsyslog package
does *not* have ExecReload set, at least not anymore.
The ExecReload setting was removed upstream because a "reload" means
that a daemon rereads its configuration, which it no longer does for
rsyslog.

Which means, you can't run "systemctl reload rsyslog.service".

# systemctl reload rsyslog.service
Failed to reload rsyslog.service: Job type reload is not applicable
for unit rsyslog.service.

The logrotate file for rsyslog in Debian currently uses
invoke-rc.d rsyslog rotate

This is an action only implemented by the SysV init script. That means
it currently actually relies on the SysV init script even when booted
with systemd.

In Debian, SysV init scripts are still mandatory, so this is sort-of
ok, even though I don't particularly like this situation.

A solution that would work with all init systems would be something like

kill -SIGHUP $(cat /var/run/rsyslogd.pid).

A systemd-only solution would look like this:

systemctl kill -s HUP rsyslog.service
