Its been a while since I used LineageOS on my OG Pixel (sailfish). I remember you have to install the custom bootloader like TWRP to flash the ROM and there was this thing with A and B partitions. Not sure if things change…
With an unlocked bootloader, whoever gets your phone can do the weird Vol Up + Power button combos to flash enter the TWRP bootloader. I couldnt recall correctly, but it is possible they can view / delete your data right within the TWRP screen. Not sure about transferring them off of your device.
OTOH, a locked bootloader wouldnt allow you to do this. There is no way to enter a flash a different ROM.
The thing with unlocked bootloader like LineageOS, especially in my case an OG Pixel, is that you can still flash the official Pixel OS in case Lineage starts to mess things up. LineageOS leaves the bootloader unlocked, so you can still flash.
I’m talking about the case where your phone is completely bricked, i.e. cannot open phone. So you can just use platform-tools to reflash. With Graphene, i guess it is more difficult in this case?

Custom recovery on bootloader-unlockable devices is required if you want to do everything on-device. You can still flash ROMs without a custom recovery. I don’t have a custom recovery on my P9PXL, but that’s only because there isn’t one…
Workarounds on locked devices usually install a custom recovery as part of that workaround. Last night, I installed LOS on one of my kids’ old Kindle Fire tablets. Amazon makes it really difficult, there’s a whole series of scripts and commands just to get TWRP installed. But once that’s done, you can load a ROM and flash it on-device.
