How can one control/kill sedum that has become invasive in the lawn which is in a residential area?

You can try glyphosate but it may or may not work. Sedum is difficult to kill. but glyphosate will kill the grass. Another choice is to put in some kind of a lawn edging between the bed and the lawn. Hand-remove anything in the lawn. Check once a week and remove anything that is climbing over. Or make the border wider to include more of the sedum.
There is not going to be any simple or easy solution.
