From memory the speeding up happened in the inner solar system.
Not likely any planet 9 is hiding there.

The wiki page says Oumuamua experienced a "non-gravitational" acceleration
amounting to about 17 m/sec in mid 2018 nr its closest approach to the sun.

The "non-gravitational" acc was similar to cometary boosts from
solar radiation and/or outgassing -- it was not smooth like gravity
but happened in a series of jolts.

So really not likely due to any hidden planet either in the outer solar
system or near the sun.
