For more advanced setups use the real Debian installer instead, it can re-use existing LVM groups and volumes and RAID arrays (but not existing LUKS encrypted volumes).
I do not know what is the name of it, but developers have implemented PV detection and "button" to create VG, which doens't create anything, but it does exist.

LVM command line utilities are available in the Debian installer.
"May be" during installation is not an option. LVM command line utilities MUST be available. At least to check names and modify if necessary.
Because to create LVM one needs to type less then 10 commands. It is much easy then to click and guess what is where in "pseudo graphical installer", which ask to write LVM formatting to the disk first and then change it. I do not understand it at all. No need to write anything - all it needs to do is to provide summary of PV, VG and LV - and ask user to confirm

Because it doesn't have windows. It is not possible to open terminal and check disk or current lvm settings
It did not detect my touch pad and I had to use tab and it is awfully designed, disk management for example.

I agree with you here. But ubuntu installer has option to use existing partitions and it shows all of them to user and ask if one wants to format them or not. One can even change something in them.
I never allowed installer to do partitioning for me, it is much easy to do manually. But installer must detect and provide option to use existing in regular Linux desktop window system, where one can resize or check something in internet or in console.
It is nearly 2020.
