Can LVM help to separate `/home` and `/` in the same partition for protecting one from the other?
I installed Lubuntu without partitioning my hard drive. Now there is one partition for UEFI, and one partition for anything else on the hard drive, wherein there is a swap file half size of my RAM.
I heard that it is important to separate
/homeand/into different partitions? For example, for protection of the data in/home, in case something goes wrong in/. Correct?
If yes, can LVM help to separate the current
/homeand/on my disk for that purpose, given that/homeand/are in the same partition right now?
I also consider if it is worth to create a swap partition twice size as my RAM, for suspending Lubuntu purpose. Can LVM also help to create a swap partition on top of the partition?
I haven't used LVM before, so just want to know if LVM can help to solve the above two problems without the hassle of repartitioning the hard drive? Or do I have to repartition my hard drive into a partition for / and a partition for /home, most likely by reinstalling Lubuntu?
Thanks.

There's all sorts of discussion about this very subject, and most of it gets marked as "primarily opinion based" I ran for a long time with just a single partition - it works well. I now keep "/home" in a separate partition, because I can tell Ubuntu to erase "/" and reinstall, without affected the files in "/home". You should consider a backup plan (regular backups) to protect the data in "/home".

Please try to re-understand my post. I have already installed everything into a single partition, now I want to protect/and/homefrom each other, can LVM help or do I need to repartition the hard drive into a partition for/and a partition for/home(most likely by reinstalling Lubuntu)?

You don't have a lot of data on your system yet, it will probably be easier to re-install - You can add LVM at that point if you decide you need it. LVM can manage all of this for you, but it may be like driving a dump truck, when you need a pickup truck.
