My advice is different than a lot of what is here. My suggestion (engineer turned exec turned investor after some exits) is to speak with the team lead directly about the issues you're having with their leadership. Try to be clear and be sure to present what your ideal best-solution would have been for 1 or 2 cases where you've had issues.
Either in parallel or after, depending on how the talk goes, also speak with the founders about your issues. If you're solving the big hairy problems for the business, you could suggest a role that's tailor-made to your strong suits (not working with a team lead, not needing to supervise engineers, whatever it is you want). In any case, any founder worth their weight in salt would want to hear that their star engineer is not getting along with a team lead. If it was me as the founder, I'd take your feedback and then solicit more from other people on the team and then make a call as to where the "fit" seems off.
As to burnout, if you've "solved" the big problems and are giving the company a pathway to revenue/profitability/etc. then I would strongly suggest you don't quit. You're well on the way to being indispensable and can use that as leverage in any future salary/role discussions. At the very least, tell the founders where you're at and say you want a vacation.
