I think the Viabtc pool is the best option where to mine Doge and LTC unless the LTE you said above is a different coin?
ViaBTC also has merge mining meaning while you are mining LTC you can also get rewarded with Dogecoin which is available in the PPLNS method.

KYC is not the only reason why to avoid antpool, there fee structure is scammy at best, while their FPPS fee is normal (4% which is the norm today), their PPLNS fee is sold as "free" when in fact, they keep 100% of the fee rewards, so in most cases, you end up paying a lot more fees than mining on another PPLNS pool, so be careful when you chose your payout method, never do PPLNS with Antpool.
