Yes, first time I deployed OpenShift I was very puzzled. But after
trying other Kubernetes deployment I think that works well and have a
lot of stuff that will help you to manage Kubernetes.
First problem I see, you shared us a 3.6 documentation link but, if you
use Origin, the default behaviour is to deploy 3.7 docker images and it
could make the deployment fail.

OpenShift is an extension over Kubernetes. Do you want to use
Kubernetes? Just use "kubectl" client instead of "oc" client.
Do you need something that OpenShift offers in the box like routes,
pipelines, ...? Use oc client.

Please, share us last ansible error and inventory file. Maybe we can
help you.

Everything is difficult until you learn it. ;-)
If you finally decide not to using openshift, kubespray is my second
better friend ... but it is also ansible based and you will need to
install manually a lot of stuff that openshift offers you in the box.
IMHO OpenShift today is the better choice.
