Did you format the drive with GUID / Journaled Extended?
If you have Windows previously, it might be formatted to MBR. You'll have to convert it to GUID if you want to keep Windows.
Otherwise, select drive from the root and formatted it.
PS: is your system 3440 or 3400? 3440 is a totally different system (Haswell) and you should create a new topic for it
download IORegistryExplorer.app. Launch it, save it, compress it. Then attach it here.
Make sure the USB-C display is connected when you save the file
Try this config
config.plist.zip
Not familiar with this image. Try using gibMacOS. You can find guide on google. Then use the same EFI you have now

Hmm, don't remember having SSDT in ACPI/Windows....I must be testing something and left them there. YES, remove them all.
I had tested files, no issue on my E7270.
How is your installer created?
Can you post the full system specs just to confirm?
Problem is it's not seeing your USB installer.
Go ahead and remove these and try different USB ports:
AirportBrcmFixup
BrcmBluetoothInjector
BrcmFirmwareData
BrcmPatchRAM2
FakePCIID_Broadcom_WiFi
FakePCIID
