Yes, your connecting rod can get bent from bad valve springs, but it's unlikely. And you should've asked the technician how did he know your rod was bent due to Hydro lock?
When valve springs go bad they allow the valve to float, which hits the top of the piston at top dead center. Most times it will punch a whole in the piston and sometimes break the head of the valve off. If your engine was revving at high rpms when this occurred, then it is possible the rod would get bent. But there would have to be evidence of this happening inside of the cylinder. (Broke valve head, damaged piston/cylinder walls, etc.)
