Not shure if I understand you correctly. You modified the *logical*
volumes. This process does not modify the LVM and the physical partition
on the disk (sda1). Now there is space in the LVM to create just another
logical volume, but that is not what you want.

If you wish to create an additional non-LVM you have to create
a /dev/sda2 which in turn requires to modify (shrink) the /dev/sda1
partition where the LVM is located. I don't know if there are tools
available to do that in a safe manner. You may check man pvresize

Regarding swap you may disable swap in fstab and simply delete the lv.
When you are finished you may recreate and enable it.
