Since after chroot the environment of LiveCD is not important any more (except the running kernel, of course), you could simply use the installation CD and a hardened stage3. If you are not trying to use SELinux, this should be enough. > After I made the LiveUSB, disabling the UEFI boot, I finally boot into the > Gentoo kernel.

You can get the firmware files from the git tree of linux-firmware project (browsable online). Then you can transfer them into the LiveCD environment's /lib/firmware by means of a USB stick, for example, after which you simply rmmod iwlagn && modprobe iwlagn. Also, before you finally reboot to finish the installation make sure you emerge linux-firmware, so that the required firmware files are installed into the target system. Hope this information helps~
