Did the refrigerant discharge suddenly through your breach as a pressurized gas? It would have been very dramatic and loud.

The fact that you show a question mark in your illustration, and say "It seems.." makes me wonder how you could be at all unsure.

Depending on the cost of the refrigerator, it might cost more to fix it than to get a new refrigerator. The line would have to be patched and the refrigerator recharged with refrigerant (and perhaps lubricant also).
