There is no easy way. If you boot into a live/rescue environment and
run parted you *may* be able to shrink your LVM and grow your /boot
but it's a procedure fraught with danger; make sure you have
excellent backups first.
I am not 100% sure that parted can handle partitions that are used
as LVM PVs.

This won't work because your /home is an LVM logical volume. Its
actual extents could be all over sda3.

parted can move partitions about, so if you run it from outside your
install and it does support LVM PV then it might work. You'd
basically have to shift everything up the disk, making your PV
(sda3) slightly smaller in the process.
I really wouldn't like to try it myself. With the backup that you'll
need you may as well just reinstall as even if parted can do this it
will take some time for it to rewrite all that data.
This is a great example of why it's not good to be stingy with the
size of /boot.
Cheers,
Andy
