Lotus does not drain Archons. She drains Archon Shards as a substitute power source because she lost hers to Ballas.
Thats how Archon Shards work. An alternate power source that can bring dead Sentients to life or in the case of the Lotus, capable of giving her more time to live until she can get her power back.
The Zariman crew is dead. They are remade by Void energy using Conceptual Embodiment. They are beings of the Void now. Lotus, just like any Sentient that attacked the Origin System, suffered damage to its reproductive capabilities. That's it. No such thing as being Void tainted.
The Lotus and the Zariman Crew are completly different in how the Void modified them.
