We don't know for certain if it works properly for Toys&Love. We don't know if can cause problems when combined with FNIS, or NOT combined with FNIS. Officially, the requirement for Toys is FNIS since that's what we are able to support. There are reports of it working fine with Nemesis though.
Seems that people who know what they are doing, have Nemesis working with Toys&Love just fine, but it's not easy to get right. Most often they also use FNIS. Why? Probably still needed for creature animations? Toys&Love, with WildLife installed, supports creatures.
Basically, use Nemesis at your own risk. We recommend you only use it if you use a mod that cannot work without it, otherwise pointless to run both FNIS and Nemesis at the same time.
