Yes.5e OGL? Would this be non DMs Guild products?
Correct. DM's Guild are not under the OGL, they have a separate license. My understanding is they can use certain D&D IP like specific official setting stuff and art in their products in return for 50% of all revenue, exclusive selling on DM's Guild, and the license is subject to revocation and change by WotC.5e OGL? Would this be non DMs Guild products?
