No. You're focusing too much on the word "
collusion," and Mueller did not call anything a lie.
Robert Mueller's report did not address "
collusion," because that is not a legal term. The Mueller probe concerned whether or not the evidence was sufficient enough to charge any member of the Trump campaign with taking part in a criminal conspiracy. Mueller determined that it was not.
However, Mueller later added that, "
The president was not exculpated for the acts that he allegedly committed."
‘We focused on whether the evidence was sufficient to charge any member of the campaign with taking part in a criminal conspiracy. It was not.’

You are exaggerating the extent to which Mueller's report exonerated Trump.
