Which command will show all the logical volumes, filesystem mount points, and the volume group in which they reside?

lslv -al displays attributes of a single specified logical volume but does not enumerate all logical volumes across all volume groups with their mount points.

mount -v shows currently mounted filesystems but provides no information about the volume group each logical volume belongs to.

df -vAg reports filesystem disk usage statistics but does not display the logical volume to volume group relationship.

The command lsvg lists all volume groups on the system, and piping that output to lsvg -il causes each volume group name to be passed via stdin (-i flag) to lsvg, which then lists (-l flag) all logical volumes within each group including their mount points and parent volume group, satisfying all three requirements in the question.
