You don’t need LCA for L1B.
If you are going for L1B there are rules like minimum 1 year of employment with the applying employer and all those. Be careful with the terms. L1 is for specialized skills with inhouse skills of the company. You cannot apply L1 with skills of just open source technologies.

To qualify for L-1 classification in this category, the employer must:
Have a qualifying relationship with a foreign company (parent company, branch, subsidiary, or affiliate, collectively referred to as qualifying organizations); and
Currently be, or will be, doing business as an employer in the United States and in at least one other country directly or through a qualifying organization for the duration of the beneficiary’s stay in the United States as an L-1. While the business must be viable, there is no requirement that it be engaged in international trade.
To qualify, the named employee must also:
Generally have been working for a qualifying organization abroad for one continuous year within the three years immediately preceding his or her admission to the United States; and
Be seeking to enter the United States to provide services in a specialized knowledge capacity to a branch of the same employer or one of its qualifying organizations.
[b]Specialized knowledge [/b]means either special knowledge possessed by an individual of the petitioning organization’s product, service, research, equipment, techniques, management, or other interests and its application in international markets, or an advanced level of knowledge or expertise in the organization’s processes and procedures (See 8 CFR 214.2(l)(1)(ii)(D)).
