I just found a typo in Windows 10 TP

Lee, I don't see the third "l"....

Nope. The problem is the unnecessary comma before the subject.

It says "To do her best work, she'll..." it should be "To do her best work she'll..."

EDIT (after squinting a bit more) perhaps it is a period not a comma. There should not be either in any case.

Both are grammatically correct. Typically, commas are more frequently used in academic writing than in casual writing.

However, have you seen the way some people text?
Some times I can't even decipher what my kids are trying to 'say' when they text me! :)
