The magic of protein folding is that you have a machine that can create a 2D string of amino acids gives you a 3D protein with a stable shape and reliably the same shape. For that to happen you likely inherently require that the 2D string
No, strings are 1D, not 2D. Sheets are 2D.
And, of course, we can see that the ammino acid molecules that the “strings” are made of were 3D to begin with (not 2D), meaning that the strings are 3D too if you look closely enough. We can only call strings (nearly) 1D because the other two dimensions are small enough to be negligible for some purposes.

Yes, you are right.
The important aspect is that the ribosome can add one amino acid at a time to the string and once it’s finished the string can fold into the 3D shape.
