Surge suppressors that use the AC wall outlet for ground are essentially

smaller spikes on the AC line caused by appliance motors etc... can be
shunted, but not a huge current induced by a nearby lightning strike.

There is much good technical information at Polyphasor's web site which will
keep you busy with your research for some time.

You might want to spell their name correctly when recommending them.

Good products, we use them exclusively where I work, and their products
work superbly. We get a lot of lightning strikes in the Gulf of Mexico
area. They have saved us and the taxpayers many hundred's of thousands
of dollars.
