My lilac tree is about five years old. Today I noticed that some of the
leaves have been partially eaten, by some insect or grub which was not
present when I looked. Is this damage/infestation likely to be serious, and
if so how can I treat it?

Probably not. I have quite a lot of different plants like that, and
it is rarely worth bothering to deal with. Most plants are well
adapted to losing a few leaves.
