I always hear that it’s bad for lithium batteries to charge over 90% or over 90% so why is there no setting to stop charging after a certain threshold on my phone, kindle, pc or e-skate?

My laptop is set to charge to only 60%, and I can set it to 80 or 100 if I need more life. As others have said, your displayed 100% very well might just be not actually 100% of the battery’s capacity.
