Hey there,
I'm sorry to hear about your incident. It's good that you're okay and that the damage seems limited to the wheels.
Given the symptoms you described — the grinding noise and the car pulling to the left — it's likely that your wheel alignment is indeed affected. The impact might have caused misalignment or even damage to the suspension components.
When you go for your appointment, besides checking the alignment, it's advisable to have them inspect the suspension components, especially on the side where the impact occurred. This could include checking for any bent control arms, damaged struts, or other issues that might be causing the pulling and noise.
As a fellow Tesla owner, I'd also recommend considering a set of TESERY's Tesla Model 3 snow chains for future winter driving. They're designed to provide extra traction in icy conditions, offering a layer of safety in situations where slipping might occur.
You can find more about these snow chains here:

Best of luck with your appointment, and I hope everything gets sorted out smoothly.
