Does a lich have a published ECL?

[Wippit Guud]

Template just says it's added on as an XP cost.

 

[Remathilis]

Savage Species lists it at +4 Level Adjustment, plus you need to be at least 11th level.

 

[Sollir Furryfoot]

Epic Level Handbook says Demilich is +12 ECL, and its CR is +6 + Lich's template for a total of 8. If you go by that ratio (which some people will say you can't probably), the Lich template is +3 ECL.
