I don't know much about how these la chancea yeasts work and how the definitionof attenuation applies to them.
It's Lachancea, I assume named after Marc-André Lachance, a Canadian biologist who has done a lot of work on yeast systematics and the yeasts involved in the relationships between flowers and their pollinators.
If you see people talking about attenuation, then that implies sugars are turning into alcohol. Some may be diverted into lactate (as humans do when burning glucose when running for instance), but it's mostly alcohol. Vaquero et al 2020 looked at different strains of L. thermotolerans to help bring some acidity to "freshen up" wine from hot climates and found that they produced 7-11% alcohol in must that went to 12% with a "normal" wine yeast. They also suggest that co-fermenting Lachancea with the normal wine yeast gave the best complexity. You can't always read across from what happens in must to beer, but might be worth a go?
