The OpenLayers configurations that consume these tiles have custom min/max resolutions defined, not web mercator zoom levels.

I am not sure if the OP is talking about TMS or WMTS:<br>
<br>
<a href="https://www.ogc.org/standards/wmts/" rel="noreferrer" target="_blank">https://www.ogc.org/standards/wmts/</a><br>
<br>
With the phrase XYZ tiles, I suspect TMS:<br>
<br>
<a href="https://en.wikipedia.org/wiki/Tile_Map_Service" rel="noreferrer" target="_blank">https://en.wikipedia.org/wiki/Tile_Map_Service</a><br>
<br>
As I understand it, TMS is 3857, and WMTS can carry a CRS.<br>
