Is there a tool in MicroStation that will let me delete colinear/redundant vertices?
You might want to try using the Cleanup Mesh tool before extracting the boundary. If you check the Coplanar and collinear options it will simplify the mesh and then the extracted boundary should be cleaner.
I would just make a copy of the mesh, apply the Cleanup Mesh tool to the mesh copy, extract it's boundary, and delete the mesh copy.
if the mesh simplify solution doesnt work for you ....
Then if the line is as obvious as it looks in you example ( which I doubt) you could just trace over it using only the verticies that look inflected...
if however its too many .ie more than 50 then ....->.
What about extracting the coordiantes from the properties then pasting into excel you could then filter the angle column and just get the coords or the inflected points
Then make new table and redraw the line with script file using the coordinates and plaqce line comand or place points via import coordinates and redraw the line via the points...
Without a real world example its a little difficult.. perhaps you could post your real dgn and we could have a play with it...
Here is my simple example of extracting the points of a string I made by hand ( I think it only works with strings I havent tried curves etc)
click on the dots in Geometry > segments and new table pops up which can be selected and copy pasted into excel but it doesnt copy the headings you need to insert a blank line and fill in your self in excel... see column direction when this has a change from the previous its the inflecton if its not the same value as the one preceding it...
So filter in excel will list them or you can just write equations to find the change pretty easy in excel....

Not too sure exactly what type of elements was produced after your extraction of the mesh boundary. You might find the Facet Curve tool that can be found under the Curve Utilities helpful. It allows you to convert curved elements to other types of elements using various methods to possibly reduce the amount of points or specific various distances for those points.
Sets how the dropped element is constructed.
Sets the element type to which the selected B-spline curve is converted.
Sets the:
Number of points when Method is set to Equal Parametric Length.
Arc length when Method is set to Equal Arc Length.
If on, the original B-spline curve is retained.
