The short answer, the exact fee, and the steps to file in Connecticut.
Forming an LLC in Connecticut costs $120 up front for the Certificate of Organization, on the pricier side compared with most other states. Connecticut charges a moderate recurring fee that is easy to plan around, and the rest of the process is the same paperwork every state requires: a registered agent, an operating agreement, and a free EIN.
The Connecticut Secretary of State collects $120 when you file the Certificate of Organization. Budget a registered-agent service on top of that if you want a local address on file without using your own; that typically runs a few hundred dollars a year nationally, separate from anything Connecticut itself charges. On the recurring side, Connecticut charges a moderate recurring fee that is easy to plan around ($80).

By default, Connecticut taxes an LLC the same way it would tax a sole proprietorship or partnership: profit passes through to your personal return and there is no separate LLC-level tax just for choosing the structure. Some Connecticut LLC owners later elect S-corp tax treatment once profit is consistently high enough to make the extra payroll paperwork worth it. Run your Connecticut numbers through the LLC tax calculator and the LLC vs sole proprietor calculator before you find your break-even point for S-corp election.
Connecticut does not require you to file an operating agreement with the state, but skipping one leaves your LLC governed by Connecticut's default LLC statute, which may not match how you actually want to run the business.

No. Most people file the Certificate of Organization themselves directly with Connecticut's Secretary of State. A lawyer can help with a custom operating agreement for a Connecticut LLC or a more complex ownership setup, but Connecticut does not require one to form the LLC itself.
Connecticut charges a moderate recurring fee that is easy to plan around, currently $80 on the recurring schedule the state sets, on top of the original filing fee.
Usually not, unless you have a specific reason like Connecticut's legal system or tax treatment. If your business actually operates somewhere other than Connecticut, you will likely need to register as a foreign LLC there too, which means paying Connecticut and that other state instead of just one.
