I will be creating a small tube styled piece to use as a junction between two pieces of plastic. The idea is to reattach the two pieces and provide strength so they don't break apart again. I plan on using PLA. My question is, will superglue (cyanoacrylate) work best for this or are there better choices for attaching PLA to hard (injected molded) plastic? The big thing I'm wanting to make sure is if any of these glues will dissolve the PLA and whether some glues might bond better than others.

Yes Super Glue is best choice. I personally use it in many PLA projects. I even apply Super Glue layer to ABS prints to avoid layer separation.

It works well with both ABS and PLA, but exercise some caution whilst using Super Glue because it produces very bad tear gas. Use it in a well ventilated area.
