How to overcome "No Research Experience" in CS Ph.D applications
If you need research experience for a program, then you need research experience and there's not much you can do about it besides gaining that experience. Even if you did gain entry into such a program, you will lack the research skills of your peers. You'll be starting off on the back foot.

A PhD is a long-term commitment to poorly paid slave labour. What if you find out you don't even like research, 1 year in? I would strongly advise the "try before you buy" approach. Get a Master's degree or a postgraduate diploma, that has a reasonable research component.

A good PhD program will want you to prove that you have the commitment and research skills to pull it off. Once you can do that, you have a good chance for admission. If research experience is a requirement, then you can't just shrug it off.
