An LLC is a pass-through entity for tax purposes, so the state taxation rate where your LLC is formed does not matter -- the revenue and expenses flow through back to the owner, wherever that owner is located. So if you live in California and have a Wyoming LLC (a good location, actually) you pay California state tax on your online Wyoming LLC income.
Nevada and Delaware both have annual maintenance and fees; if someone tells you that a Nevada or Delaware entity is your best choice without asking you a lot of questions about what you intend to do, projected income, and long term plans, then you are getting advice from a talking parrot.
