Nope, not at all. Antifreeze just contains corrosion inhibitors.
Electrolysis in this context is a fancy way to describe corrosion, but your source may be implying corrosion induced by an outside electrical source, like connecting the radiator to the chassis which is connected to the negative battery terminal. That could speed things up, though all corrosive substances already generate electricity on their own. Common batteries work by harnessing the power of corrosion. Lead-acid batteries use sulphuric acid and lead, for example.
But yeah, all antifreeze has additives to inhibit corrosion. They could be sacrificial materials that corrode more easily than the metal in your radiator (and so take preference) or they may be materials that inhibit the chemical oxidation process or they could be both.

"Electrolysis" is a misleading term if you're talking about materials and not electricity. Just say "corrosion".
The only reason I could think of worrying about any metal in the cooling system is because it corrodes more easily than a different one or because two different metals are touching each-other, which accelerates corrosion. In either case anything in contact with antifreeze should be safe.
If, however, the part you install is grounded when the normal part isn't, like an all-metal radiator bolted to the chassis instead of the stock one with plastic ends, then maybe corrosion caused by electricity is a concern.
