Computer help needed due to lightening strike

I do have surge protectors on all of my electrical components (thank God) but dont know of anything for the phone lines.

If a protector does not have a short connection to earth, then it does not do nor claims protection. All phone lines already have the best protector installed for free by your telco. Surges seek earth ground. A path to earth from the telephone pole was down (now damage) wires, into the 'whole house' protector, and then to earth.

You should inspect that telco installed protector (or the telco installers replaced it).

To have damage means a surge must have both an incoming path and a separate outgoing path to earth. Best path through computer modem and router would be incoming on AC mains. Then outgoing to earth via interior phone lines to that 'whole house' protector.

If both paths do not exist, then no damage. For example, the surge was (beyond doubt) incoming to the computer. But what was the outgoing path? If via the ethernet port, that only that part is damaged. Computers already have some of the best protection internally. But sometimes a protector too close to a computer and too far from earth ground can compromise (bypass) that protection.

Surge does not destroy everything. It only damages a part that was in that incoming to outgoing path. Most all surge damaged electronics have very few or only one damaged part.

Apparently secondary protection was missing (ie earthed a 'whole house' protector from any of more responsible companies). And your primary protection system was missing. All others could learn from your experience. Surges went searching for earth inside your house if this critical connection was missing. A picture of what to inspect:
