As best I recall, there's no support in the UI for LVM volumes with RAID level. (And I don't see any such option in the kickstart documentation, which also suggests that it won't be present in the UI.) The supported configuration is to create two partitions, create a RAID1 volume from those, make that volume an LVM physical volume, and then any logical volumes in that VG will be backed by a RAID1 set.
Which is *stupid*. Why would you not want the LVM on a single RAID1?
I don't think I follow you. What I described creates a single RAID1 volume, and then creates logical volumes within it.
I don't seem to see your how-to-do-it today. All I know is that the GUI partitioner lets me *either* to lvm, *or* RAID, which results in two RAID partitions (root and swap), not one LVM on top of a single RAID 1 partition.

LVM on a Linux software RAID1 is still easy to create. Here is a link to a tutorial someone made with screenshots.

Although I don't use LVM much I do use Linux software RAID1 on all my production systems. I have a few dozen systems that use it under CentOS 6 and 7. It has always worked just fine and has saved me trouble from failing disks on quite a few occasions throughout the years.
