The benefits and drawbacks of LVM for a single volume are independent of
whether the LVM lives on a RAID.

Yes.

When you get to the partitioning page of the installer, select Custom.
Then nothing is created initially.

True enough that it's not intuitive. But it's not that hard, once you
see the process.
1. Create RAID partitions on all relevant devices. If you want a
LVM, be sure to create separate sets of partitions one partition
on each disk for each RAID device) for /boot and the LVM.
2. Create RAID devices, which group the partition sets (one for
the /boot partitions and one for the LVM, if you do it that
way).
3. Create the filesystems and/or LVM physical volumes on the
appropriate RAID devices.
4. Create the volume groups and logical volumes for the LVM.
