Systemd-resolved can't actually see your leases all on its own; the DHCP client needs to provide it that information. Networkd and NetworkManager do it directly through the D-Bus IPC.
For standalone dhcpcd, you would likely need to install the `resolvconf` emulation that comes with systemd (usually packaged separately to avoid conflicts with the real resolvconf/openresolv), or find a hook script that would upload the configuration using resolvectl. For dhclient, probably the same.
