> has there been any discovery made with the help of a collider that found its way into an industrial product?

Yes. SLAC has an excellent public-lecture series that touches on industrial uses of particle colliders [1].

If you want a concrete example, "four basic technologies have been developed to generate EUV light sources:" (1) synchrotron radiation, (2) discharge-produced plasma, (3) free-elecron lasers (FELs) and (4) laser-produced plasma [2]. Synchrotrons are circular colliders. FELs came out of linear colliders [3]. (China has them too [4].)

We have modern semiconductors because we built colliders.
