No. Text formatting in fillable form is not something we currently support but you can add or vote on feature ideas:
If you need to add a new idea click "Create an idea" under "Actions" in the top right.
As far as the bullets point, you can try the commands key on your keyboard: on Mac hold the Option KEY down and type number 8. On PC, with your keyboard Num Lock ON, hold Alt KEY down and type number 7 or number 9.
