Dang Ryan, that phone is seriously crunched! I'll remember not to take my 6 pro when I go out near cliffs.
My first impulse is to suggest replacing the charging port. There are a lot of pins on a USB-C connector, and it's entirely possible to damage the data pins but still have the pins that carry the power be intact. Of course iFixit seems to be a little light on information about the charging port, but after watching a couple of video teardowns, it looks like there's bad news in that department.
On our phone the charging port is soldered onto the motherboard, which means you'd need someone skilled in microsoldering to be able to replace it, and of course that assumes you can find a replacement part, which may or may not be difficult. I find myself disappointed with Google for making that choice, since the charging port is heavily used and susceptible to damage.
Sorry I couldn't be more help; hopefully some of our actual repair technicians can give you more guidance.
