Correct Way to Set DNS Server

That may not work in all cases, That rule only covers UDP port 53 and DNS will sometimes use TCP.

Do you have devices on your network that have UDP blocked?
Simply make a TCP rule as well. Good catch!

Allow Both TCP and UDP Port 53 to Your DNS Servers

I have a couple of devices that don't respect my DHCP servers wishes with "option6".

You would add a DHCP Option 6 in the LuCI web GUI:

You can also give a specific DHCP reply to the particular client...

Force Google SafeSearch on Lede 17.01.4

Yes; but I'm certain you won't get the desired effect, since this servers are managed by different providers - blocking different domains. Also, here is the correct method (I realized option dns was a Boolean value): config host option ip '192.168.1.2' option mac '00:11:22:33:44:55' option name 'mypc' option dns '1' option tag 'kids_dns' config tag 'kids_dns' list dhcp_option '6,216.239.38.120,208.67.222.123,208.67.220.123' Hope this helps.
