For a lot of products produced in isolation, you should work with the LQ, not the AQL, which is designed for inspections of a continuous stream of production.
LQ stands for limiting quality. It is the quality level, for a lot in isolation, which, for the purpose of sampling inspection, is limited to a low probability of acceptance.
The tables and all the information needed to use this type of sampling plan are in the ISO 2859-2:2020 standard.
Choosing ISO 2859-1 vs. ISO 2859-2 comes with MASSIVE implications for the supplier. A not-very-good-quality batch is much more likely to get rejected if the LQ (under ISO 2859-2) is used.
This video explains these two concepts for you.
