If a company can't afford to make the legally required filiings they have no business being a publicly traded company.
A TA's job is not to raise capital or sell shares. Their job is to issue, track, and manage the issuance of shares and keep the required records. While it is the company's obligation to provide the A/S and O/S to the investing public, the TA is the only one who has the figures which count because of their SEC license. You are correct that it isn't the TA's function to provide IR for the company but no reputable company gags their TA when it comes to releasing share count information.
In this case, since the company hasn't made any of its legally required filings, there is nowhere but the TA to obtain verifiable share information.
