Firstly, we talking about new devs. Once you get a bit more experience you start making more of these calls yourself. Secondly, sanity checking an approach to solving a problem with rest of the team is just basic common sense - someone else might be solving the same problem, or have some insight into a part of the code you haven't touched, or have experience of the same issue on another team. That never goes away regardless of your level. The suggestion that you should solve problems on your own is far more harmful. Software development is a team sport.
