”Service” to me is just ”delivery of something with a specific scope and a defined contract”, not so much about who delivers said ”service”.
Many IT depts would do themselves a massive favor to deliver actual services instead of “just infra and some stuff thrown on top” and call it service delivery.
Tools like in this link can help, but a big part is simply about automation and delegation/self provisioning.

Platform as a Service or anything "as a Service" means someone else provides it as a service (ie subscription). The Platform part is all this is offering. So it is not a Platform as a Service.
