All one has is theory and common sense about the effect of LPS. Then the personal decision whether paying for a LPS is worth it is — personal.

Actually, much is known about lightning and the effectiveness of lightning protection systems.
One of the misconceptions is that lightning protection systems do not work. They have proven effective for over 200 years and they do work if they are designed, installed, and maintained according to the National Fire Protection Association-780, Standard for the Installation of Lightning Protection Systems, 2023 Edition. The Principles of Lightning Protection are discussed in Annex B.
Another reference is The Art & Science of Lightning Protection Systems, by Dr. Martin Uman, from the University of Florida who has been studying lightning for over four decades.
Also over the years there have been may studies that have proven the advocacy of LPS. One such study was conducted at the University of Florida's International Center for Lightning Research & Testing at Camp Blanding.
There are many other references and data.
As far as the newer systems which try and prevent a lightning strike, as some have commented, yes these devices are currently installed and being evaluated for their effectiveness. NASA has an elaborate setup at the cape.
