A large proportion of the trial transcripts have been put online , and there was daily court reporting. Journalists who covered the trial have continued to comment and to intervene in discussions - people like Liz Hull, Judith Moritz and Josh Halliday. It would be extraordinary if they had all, working independently, somehow managed to omit critical material which would reassure people in the hundreds of thousands of words they produced during and since the trial.
Anyway, it's hard to imagine what that reassurance could look like. There is more than enough material available on the expert witnesses' testimony, for example, for people to see the logical flaws, the unevidenced assertions, and the pseudoscience. (Transcripts at lucyletbyinnocence.com/transcripts.html). It's sobering reading. To the extent that these expert witnesses have commented since the trial, they've shown the same inability to stick to the facts and to approach problems scientifically.
The judge's summing up, the prosecution closing speech, the defence closing speech are all available on the same site. Worth reading.
The idea that, after all that, people don't have sufficient information to take a view on the soundness of the conviction, is simply not reasonable. There's a good article analysing that argument at https://jollycontrarian.com/index.php/Lucy_Letby:_you_had_to_be_there
It's absolutely your right not to take an interest in this discussion as in any other, but that doesn't make the conviction safe or the discussion unimportant. There is a great deal of information on this case in the public domain, and it casts a strong light on many problems with our justice system well beyond Lucy Letby's conviction. All worth talking about for those who are interested.
