As to lack of earth the official answer has to be rewire with earth or use class II. I would agree few people are likely to touch the lights when lit, and knowing the earth is missing likely you would always switch off before changing a bulb, but don't think if it all goes wrong courts would see it that way.
In theory I see no reason with LED switching off/on should effect them, in fact I did an experiment using a 555 timer at over driving LED's and flashing them on/off so they appeared brighter, although average still within rating for LED and that did not seem to damage them, until the average exceeded the rating of LED, when they got first dimmer then failed.
So would suspect it is a spike caused by some thing else, may not even be in your home, some one three doors away welding. But how to stop it, not so sure, maybe SPD, but can't really experiment when may LED's don't seem to blow, all I can say is I have a SPD fitted.
