TL;DR
No, no law requires a lawyer to set up a company. For a simple SASU or EURL, a platform is enough. A lawyer is recommended as soon as the articles of association bind several people: multiple shareholders, investors, a shareholders' agreement, exit clauses, contributions in kind or a holding structure. 
Service-public
When a lawyer is the right choice
- Several shareholders with different contributions or roles.
- Planned fundraising, BSPCE, preference shares.
- Contributions in kind or of a business (fonds de commerce).
- Regulated activity or a particular legal risk.
