Should the languages you speak be mentioned in your personal statement?

Possibly. You need to explain how advantageous that would be when in practice. Personally, I didn’t mention my languages and got accepted for my course. I spoke more about my different work experiences that developed me into a suitable candidate for the course.

The thing is I was meant to do way more work experience these past few months but corona kinda ruined that

The universities are aware of this and should be willing to allow it. Do you have any work experience? If not then I would probably talk about the languages.

Shadowing is good as it gives you an insight into the role, which you should reflect on in your PS. You could use the TA role to show some of your skills too, along with any other volunteering etc. you have done

I've been going to Arabic school since I was 5 (and I've just learnt the language from my parents) and I've also learnt to understand and speak quite a bit of Spanish.
